Future tech

by Drew Weber

Editor's Note: The ABA Blog is happy to introduce Drew Weber as a contributing author focusing on the intersection of technology and birding.

--=====--

The current state of birding technology is truly awesome. You might say that we are in a golden age of technology for birding, but the truth is, we can only imagine what we will soon be able to do with tech that fits in our pockets. Any time that I find myself in a crowd of birders, I am struck at how quickly birders have adopted iPhone and Android smartphones across every age group and skill level. 

Already, most of the major North American field guides have apps for iOS and Android phones, with quite a few international guide books also available. Talk about accessibility and convenience! Instead of carting along a 4-inch thick field guide on an international trip, you can load up your device with a couple apps with the most updated info (and sounds!) and be on your way.

If you are an eBird fanatic like I am, you can submit checklists straight from your smartphone with BirdsEye BirdLog, and figure out where to go birding with sightings info in the BirdsEye iOS app, Oddfeathers website or the BirdTrax Google gadget. You can get daily and hourly rarity and needs alerts from eBird and rare bird text messages from Kiwifoto.

Aba tech

And then there are all the new features that aren't even birder-centric, but have ended up being a staple of everyday birding. Pulling out a phone to digiscope with the camera or record a bird song is now a routine sight, as is sharing those recordings for instant help with identifications. Rare bird alert texting groups, maps and driving directions on smartphones, and Facebook groups for identification help and sharing photos have become commonplace in the birding world. Language translation apps promise easier social navigation and birding in other countries.

But advances aren’t just limited to smartphone apps. Birders get weekly migration updates during the spring and fall from BirdCast. We have access to real-time data on bird migration from NEXRAD radar stations and each morning birders can wake up to regional analysis by amateur radar ornithologists across the country.  Xeno-canto.org and the Macaulay Library have extensive collections of bird sounds from around the world.

Optics are ever-improving and you can pick up increasingly competent bins at almost any price point. High-end scopes and bins are pushing the envelope on strength and weight while increasing field of view and adding new coatings to increase light transmission. If you have the cash to spend, you can even buy name-brand spotting scopes with embedded cameras, or even image stabilization.

Likely some of these tools are already incorporated into your daily birding. None of the above tech advances should be particularly surprising for most avid birders, as we seem to relish finding new tools to enjoy our hobby in new and exciting ways.

I wrote this post to simply set the stage as I talk about new technology for birders in future posts. Let’s be optimistic that the new developments continue to flow in, and that they improve birding both for newcomers to birding, and those of us who have been actively birding for decades (really, decades already?). We can debate, as has been done in various articles in Birding and ABA blog posts, about whether this digital revolution is good or bad for birding, but I think that discussion is moot. The revolution is happening no matter what. Let's embrace the technology we have and work to make it have the best possible impacts on how we enjoy birding.

When people dream up new advances that will change birding, the standard answer always seems to be a device or app that identifies birds/birdsongs for you. What new tech advances are you most excited or hoping for?

From Kiptopeke to Google

by Nate Swick

There may be no technological innovation of the last decade so beloved by birders as Google Maps. We use it to find birds, to find habitats, to direct people to birds and habitats, to get directions from one hotspot to another, and on and on and on.  Without it, birding itself would likely be a much less convenient endeavor. Google is as scrupulous as companies go, and doesn't do anything without a darn good reason, but free and complete GoogleMaps may be the closest thing to corporate benevolence since that one time Starbuck's gave away free coffee.  

There are lots of birders on Google, but how many birders are actually in Google?

Google streetview, the ambitious attempt by Google to provide panoramic views of every street in the world, fairly regularly captures regular people going about their lives.  In fact, there is no shortage of websites and top 10 lists dedicated to sharing the oddest activity the Google Car - a small, white vehicle with a spherical 360 degree camera mounted to the roof - has captured as it makes its global rounds. And this past fall, at the ABA rally in Virginia, that included me.

Before the rally participants had begun to arrive I walked over to the Kiptopeke hawkwatch tower to spend a little time before the event officially kicked off. There I met Steve Kolbe, Kiptopeke Hawkwatcher, and we wiled away a couple hours watching hawks pass over and talking birds. You know, like we all do.

I first noticed the bizarre car as it tried to drive down a wide dirt trail. It's hard to miss with the aforementioned rooftop camera and the words "Google Maps" emblazoned across the side. We then watched as it turned through down the side road up into the parking lot, circled around once, and headed back out to parts unknown. 

I didn't think much of it until Steve emailed me this photo.

That's me on the right, Steve on the left, recorded for internet posterity. You can find up in actuality here.

Has anyone else been captured by Google while birding?

Do You See What I See? A New Visual Search Tool from Google

by Ann Nightingale

 

Here are two truths:
1.Some people are always looking for easier ways to do hard things.
2.Technology can be amazing.

There are a lot of people anxiously waiting for WeBIRD, the promised birdsong equivalent to Shazam and MusicID, but they may have to wait a little bit longer. Music databases can make a match to a digitally produced song, but they can’t match you singing exactly the same song. The variations in the human voice make that kind of analysis a less than exact science. A person can recognize that you are singing Happy Birthday; Shazam can’t. Similarly, there is enough variation in birdsong that it’s very difficult to get a computer to recognize the nuances. You can teach one to recognize some of the songs some of the time, but a reliable tool is not available yet.


But can we use technology to recognize visual cues and help us to ID birds? New birders are being encouraged by some to post their birding photos to the Internet in order to get an ID, instead of using field guides or birding mentors. Crowd-sourcing identification is certainly one way to handle it, but it would  be much “cleaner” if we could somehow get the computer to do the work for us, wouldn't it? Enter Google Search by Image. Seriously! You can upload an image or provide a URL to images.google.com, and Google will search for similar images. How cool is that! Just click on the little camera at the right of the search field and follow the instructions.


Google search bar


When I learned of this, I knew an experiment was in order! I uploaded a picture of a Hermit Thrush, clicked “Search” and waited to see how Google would handle the difficult Catharus species challenge. My uploaded image shows at the top of the screenshot below:


Hermit thrush image

Can you say “Epic Fail”? None of these pictures is even close, except for the background colour tones. None were even of birds, let alone thrushes. I guess I should have expected that. Maybe it was much too challenging. How about something simpler, like a Barred Owl? The Internet is crawling with owl pictures. This should be easy!

Barred owl image
Sigh… Not even a little bit better. More diversity in the selection of “matches”, but still no birds and certainly no owls. Maybe the whole bird has to be visible. Here’s a Burrowing Owl, Google. What can you do with this?

Burrowing Owl image
Um, no. But it’s interesting to see how many celebrities resemble Burrowing Owls. Brangelina? The algorithm seemed to be focussing on color-matching. What about a bird with a distinctive color and shape? Easy--Great Blue Heron!

Great Blue Heron image

Eureka! It matched one! Admittedly it’s the fifth image the program chose, and it somehow thought that a better match for my heron was a staged suicide scene ( in the top row), but at least it got a bird, and the right bird at that!


I was prepared to completely dismiss this function as useless, but then an interesting thing happened. A birder from Ontario sent me a picture he took while visiting Vancouver to see the Red-flanked Bluetail. It was a great photo of a bird that he (and those I showed it to) identified as a Veery, an almost unimaginable bird to be in Vancouver this time of year. But with a Brambling and a Bluetail around, never say never, right?


People send me pictures all the time, but there was something about this report that made me suspicious. Spidey-sense, some people call it. I asked for more information, which did not come. I did a little online detective work and didn’t find anything reassuring. So I posted the report--along with my reservations--on the Vancouver birding bulletin boards, mindful of those who think that all rare birds should be reported and not wanting anyone to miss out on this potential rarity. Then I remembered the Google Search by Image tool. I uploaded my suspect image--another Catharus--and guess what? Here are the results:

Veery image

Epic win! The person reporting this bird was a prankster (very funny-not!), my spidey-sense was on the mark, and within seconds, Google found the image in an almost-two-year-old blog post from Massachusetts. I don’t know what motivated the hoax, but I’m delighted that the perpetrator was found out before an onslaught of inevitably frustrated birders wasted their time.


For bird ID, Google Search by Image has a very long way to go. There are some things that humans can still do better than our current technology. But today, I, and all my lookalikes below,  are giving a big alula up to Google!Ann image

Count Circle

by Bill Schmoker

Stevens Creek Software has just introduced Count Circle, a new birding app with a simple but interesting premise of showing the boundaries of established or potential Christmas Bird Count circles on an iOS (Apple mobile) device.  If the device also has GPS (such as an iPhone), you can see where you are relative to a circle in real time, something I know I could have used in the past when wandering near the edges of a count, especially one new to me.  

Instead of wasting time with a Gazetteer and trying to triangulate landmarks, intersections, etc. I could just peek on the screen to see if I was still inbounds.  The app also looks great for scouting, especially when switching from the map to the satellite view which gives away habitat changes, fence lines, and back roads or even trails beyond the cutoff of "normal" mappability. If the count is already in the National Audubon database you can just pull it up from the state-by-state menu. If you notice the center is off (Audubon's database is only as good as the submitted circle coordinates, often estimated from old maps), then you can drag the center to what you deem is the correct place.

Additionally, you can choose your own center (if, for example you are contemplating a new count circle and would like to experiment with boundary possibilities) and it will scribe the 7.5 mile radius for you.  You can also set a different radius for different purposes.  For example, maybe I'd like to do a local patch big year within 1 km from my house- the app allows for that.   Anyway, for $2.99 looks like a neat tool to add to the mobile-tech birding arsenal.

Looking under the listings for Colorado, I can find the count I compile (Boulder.)

 

 

Photo8
Pulling it up, I can see the overview of the whole count circle.

 

 

Photo9
I can also zoom way in.  For example, I can see that most of Allens Lake / Lake of the Pines near the north side of the circle is inbounds, though the north shore isn't.

 

 

Photo
Maybe I'd like to see what a count circle centered on Hayden Lake would look like.

 

 

Photo2
I just drag cross hairs to where I'd like my center to be and it will drop a pin there.

 

 

Photo3
I can look at the big picture and re-adjust my center as desired.

 

 

Photo4
Or I can zoom to more detail, in this case noting that if I'm heading up Highway 35, the circle ends just past the unnamed pond, right the road bends northward to cross the river.

Here's their press release:

Cupertino, California, January 22, 2013 – Stevens Creek Software, whose popular Birdwatcher's Diary app is used by birders to record and report their sightings, has released its latest iOS app – Count Circle. Count Circle contains the complete National Audubon Society (NAS) database of Christmas Bird Count (CBC) circles, with a total of 2429 different count circles in 72 different states and territories including Canada, Mexico, the Caribbean, South America, and Antarctica. Using Count Circle birders can lookup and display any count circle on an interactive map, and find out exactly what is (and is not) included in the circle. Units which have GPS capability also display the user's current location, so that during a count they can determine precisely whether they are inside or outside the circle.

 

Although the app was released too late for this year's round of Christmas Bird Counts (which were the genesis of the idea for the app), it came just in time for the latest "Patch Challenge" being held in Texas, in which birders see how many species they can find in a 7.5-mile radius circle centered on their own home. Count Circle not only lets users create and save their own circles, it also lets them set a different radius (in miles or kilometers) should they wish to do "Patch Challenges" with more limited (or wider!) geographical scope.

 

Much of the data describing the locations of the circles in the NAS database seem to have been obtained before the widespread availability of GPS devices, and do not accurately reflect the correct center of the circles that are being surveyed. Count Circle lets count organizers relocate their circles, both to obtain accurate values for the centers currently being used, and to experiment with minor shifts in the center which might allow key bird areas to fall within the circle. The software even allows organizers to report such changes directly to NAS.

 

Christmas Bird Counts, along with the Breeding Bird Survey series that occurs in the late spring, are a key scientific tool in understanding bird populations and migration. Count Circle is designed as a tool not only to make those surveys more accurate, but also to encourage more birders to participate in them. Stevens Creek Software's other birding app, Birdwatcher's Diary, has already proven invaluable during CBCs in making the process of recording counts quick and accurate. The overwhelming response to the initial release of Count Circle suggests that it will become another valuable tool in the birder's software toolbox. 

 

Pricing and Availability:

The Stevens Creek Software web site, provides full information on all of Count Circle's features.  The app runs on all iOS devices 4.3 or later, is available for $2.99 (USD) and is priced accordingly in other regions.

Help Monitor the Red Crossbill Invasion

by Nate Swick

Birders in the eastern part of the continent are calling this the best winter finch winter in decades, perhaps even more amazing in that it's not even officially winter yet! Beautiful and charismatic, Evening Grosbeaks are the centerpiece of this irruption, and we recently encouraged birders seeing "Evebeaks" to be sure to get those sightings reported to eBird so that we can watch the invasion happen in real-time.

Second only to the grosbeaks in inducing excitement with their arrival are the crossbills, both White-winged and Red, that have been sweeping across the east in incredible numbers.  Much has been made of the fact that within the enigmatic species known as Red Crossbill may lie up to 10 cryptic, but full in their own right, species differentiated from one another by bill size, food preferences, and, especially, flight calls.  Indeed, many of these "types" can be confidently identified by birders paying attention to those calls.   

This season has seen reports of multiple types of Red Crossbills wherever the species has been reported.  North American Birds editor Ned Brinkley, who is based on the eastern shore of Virginia, reports that both Type 3 and Type 10 crossbills have turned up in that state this fall, neither of which have ever been recorded in the past.

Now, asking birders to note the high-pitched mutterings of birds passing overhead may sound like a sure-fire way of deadening the joy in seeing these infrequent winter visitors, but an enormous amount of information can be acquired during these finch years from regular birders noting the sounds they hear from the bird they're seeing.  Even something as simple as obtaining a recording can be a big deal, and these days most cell phones are capable of picking one up one of sufficient quality to make the ID.      

Matt Young at Cornell Lab of Ornithology has been doing great work trying to suss out the differences in Red Crossbill populations.  Earlier this fall, Matt wrote a primer posted to the eBird website laying out the differences with several incredibly useful audio examples.  Matt also encourages birders who have recorded crossbills but need a hand identifying them to type to send those recordings to him at may6 AT cornell DOT edu. 

Additionally, the ABA's journal of ornithological record, North American Birds, has been on the forefront of the crossbill ID revolution with several articles, by none other than Matt Young, focusing on status, distribution, and identification of the various types. Those posts, now suddenly exceedingly relevant, are now hosted free on the ABA site.  

Status and distribution of Type 1 Red Crossbill (Loxia curvirostra): an Appalachian Call Type? - M Young, et al  

Type 5 Red Crossbills (Loxia curvirostra) in New York: first confirmation east of the Rocky Mountains - M Young

New evidence in support of a distinctive Red Crossbill (Loxia curvirostra) Type in Newfoundland - M Young, et al

And although it scarcely needs to be said anymore, be sure to get those sightings entered into eBird.  Our knowledge of irruptive boreal finches is woefully incompletely, but phenomena like these flights offer opportunities to make inroads into our gaps in knowledge.  

Thanks, and enjoy the finches this winter!

The Espresso Book Machine

by Rick Wright

For most purposes, I'm a firm convert to the creed of the digital book. I don't much like reading on a screen, but when it comes to looking something up -- a date, a spelling, a "fact" -- it's just as easy and just as satisfying to click a couple of times as it would be to get out of my chair and walk over to the bookcase.

And, of course, there are many, many times when the book I need isn't on my shelves anyway. Nowadays, most of the time, there's no need to get in the car and drive to Princeton or New York: more and more of the print resources I rely on are available on line from such repositories as the marvelous Biodiversity Heritage Library.     

But still, there are times and there are circumstances when nothing can beat the convenience of the codex. 

I've been spending a lot of time lately thinking about sparrows. Among the many older volumes I've turned to again and again is, naturally, Robert Ridgway's Birds of North and Middle America, still -- 111 years after the publication of the first volume -- the best collection of detailed plumage descriptions available.  

5822590-L
Indeed, so useful is the book that I finally decided I needed a copy of the real thing -- paper and ink -- to sit on the corner of the desk while I work. Unfortunately, it was quickly apparent that Part I, the sparrow volume, was on the scarce side in the used book market, and expensive; $50, the best price I could find, buys a lot of macaroni (or a little bit of dog food).

Enter the Espresso Book Machine. For $23, I could have a copy of the book printed out for me at McNally Jackson (or any of another 40 or so locations in the US), and for $6 more, they'd send it to me by express mail, saving me a trip across the Hudson to pick it up. Worth a try.

8182872983_495a5fd112_z

Hurricanes and snow storms meant that the mailing wasn't as express as planned, but the book arrived, and I'm impressed. It's the same size as the original (a real brick), and the quality of the copy is as high as that of the original print (which isn't saying much, admittedly). The paper is not of the highest quality, with the yellowish tinge I associate with central European photocopies, but it's certainly acceptable, and looks better and reads easier than most of the library copies of the original printing I've seen.

My only disappointment, and a mild one, is in the binding. Perfect bindings (oh bitterly ironic name) are cheap and quick, and the weight of the book block's 700+ pages is guaranteed to break this one sooner or later.

More significantly, the openings have essentially no gutter, and though I haven't noticed any actual loss of text, there are a few letters stuck so far down in there as to be discoverable only with the aid of a flashlight. This may simply be a peculiarity of the original book (from the University of Wisconsin) from which my copy was scanned, but even if it is a result of the EBM's trimming and binding process, this problem should be less likely to arise in volumes that are less massive than this.

Many classic bird and natural history books are available this way, though the EBM website doesn't invariably make searching for them easy. Bibliographical data are few and vague for many titles, especially those published in several volumes; it took two exchanges of e-mails before McNally Jackson and I were both certain that they were producing the correct part of BNMA for me -- their selection pages list only the title of the larger work, leaving the individual volumes unidentified.  

I expect that to improve as digitization efforts grow more disciplined. Meanwhile, the EBM is a great way for the researcher to get quick, relatively inexpensive access to paper copies of important reference works many of us don't own. And next time I'm in New York, I'm going to buy something just to watch the machine work

How to Use the Intertubes, Part 1: Links

by Greg Neise

Keep 'em short and sweet

I would like to introduce myself. When you click over to ABA Birding News and send a comment or a question, I'm the guy who gets it. Since mid-August I've received nearly 1,000 messages from people reporting glitches, making suggestions (thank you!), or offering praise (double thank you!). So—having now introduced myself—I would like to share some of what I've learned, and offer some suggestions as to how you can get the most out of using the internet to enhance your birding.

USING LINKS
By far, the number one problem being reported at the moment is broken links—URLs that are copied and pasted into the body of an email message. Here's what happens:

Let's take the very worst offender, Google Maps, as an example. If you place a pin on a Google map of a rare bird sighting, for example, the link that you end up pasting in your email message will come out looking like this:

https://maps.google.com/maps/ms?msa=0&msid=204602211350579994736.000485cd5106b9960e764&ie=UTF8&t=h&ll=38.597654,-88.172836&spn=0.013416,0.025706&z=15&iwloc=0004cc6f1ef18c9f5ae77&source=embed

Note what happened here. The web application we use to run this blog (TypePad) considers the question mark used in the URL to be punctuation that ends a sentence, therefore a line-break is allowed. Many email programs do the same, and the result is that the link is broken when you send it.

But there is a very simple way to ensure that this never happens. On the Google Maps page, instead of copying the link from the address bar in your browser, click the link icon in the Google Maps tools.

Google_maps_short_url

In the screen shot above, the red arrow labeled #1 points to the link tool in Google Maps. Clicking it will open the dialog box seen to the right of the icon. Note the "Short URL" check-box (red arrow #2). Click it! The result will be a very short and friendly URL you can safely use anywhere.

Flickr presents us with the same challenge as Google Maps, but just for fun throws in a twist. In addition to having unwieldy-long URL strings, Flickr uses the "@" symbol as well. This poses a problem for us when we make list archives available to the public. We want to keep spammers from harvesting email addresses in the emails posted at Birding News, and we do this by replacing the "@" symbol with " AT " to keep robot phishing attempts from recognizing email addresses.

Because Flickr also uses this symbol in their URLs, we wind up breaking the address string. We also use our own link shortening scheme, but if the link is broken, it only recognizes the first half (this, by the way, is something we are working on handling at the moment). But Flickr too, offers a short link:

Flickr_short_url

When sharing a link to a Flickr photo in an email, always click the "Share" button in the tool bar and use the shortened link. It's easy, and everyone will love you for it.

Link shortening should be simply "what you do" when you share links via email. There's no reason not to, and every reason to use shortened URLs. Some might call this "best practices", but I tend to shy away from corporate mumbo-jumbo-speak ... it's just what you should do.

But what about links to sites that don't offer link shortening? Google offers a link shortener at http://goo.gl/, as does TinyURL, but the best is Bitly.

In addition to shortening URLs as the others above, with a Bitly account (free), you can install a plugin for your browser that allows you to shorten any URL, just as easy as using Flickr or Google Maps. It places a little Bitly button next to your address bar, which when clicked (#1)...

Bitly_short_url

... gives you all kinds of options, in a very simple pop-up dialog. Clicking the Bitly button will shorten the URL of whatever page you are looking at. Simply click the short URL (#2), and it automatically copies the link. Now you can paste it in your email. That's it!

Bitly offers other options, such as saving the shortened URL, sharing it on Facebook and more that we'll get to in another installment of How to Use the Intertubes.

Negate the Noise

by Bill Schmoker

In my last installment I talked about potentially Red-lining your ISO by setting a desired shutter speed and letting your camera's auto-ISO feature keep up by adjusting the sensitivity.  As advertisers are fond of saying, results may vary- make sure to play around with ISO on your camera to see how far you can push your sensor and still have acceptable results.  

The main issue with high-ISO settings is the image noise that can be introduced.  This is sort of like of the digital equivalent of film grain for those of us who can remember shooting slides or print film.  Basically, with faster ISO settings more random electronic noise will be introduced to the image, degrading its quality.  In general, newer cameras with later-generation sensors handle high-ISO settings with better noise control.  Larger sensors (like those found on full-sized DSLR bodies) are also generally less "noisy" than smaller sensors found on compact cameras.  Check your shooting menu- many cameras have a high-ISO noise reduction setting to help get cleaner images when you are red-lining your ISO.  Noise can be very hard to see on busy, focused backgrounds like branches, leaves, and grass, but is most noticeable in shadows and dark, out-of focus backgrounds.  

As a general rule I'd rather have sharp but noisy images instead of soft, "clean" snaps as noise can be dealt with easier than soft focus.  Here's an example of a really high-ISO shot is used in my last post, a Hermit Thrush image shot at ISO 6400.  This is what it looks like out of the camera (opened in Adobe Photoshop Elements for editing):

Screen Shot 2012-10-03 at 12.05.48 PM

Note that the picture looks a little washed out.  Composition isn't great, either, but to focus on the bird and get the metering right I centered on the adult bird.  So let's start with a more pleasing crop:

Screen Shot 2012-10-03 at 12.08.43 PM

By next going to 100% view, we can evaluate the picture.  It is pretty sharp (noting the facial feathering detail, for example) but also quite noisy (click on the image to enlarge and note the green background.)  Realistically, this wouldn't make a great cover shot for the next Birding Magazine, but all hope is not lost...

Screen Shot 2012-10-03 at 12.39.04 PM

The first thing I suggest is running a noise reduction filter.  I use NoiseWare, which runs as a plug-in from the filters menu in Photoshop or Photoshop Elements.  There are certainly other options, either as built-in features in photo editing software or as aftermarket products.  Most of the time with NoiseWare I find the default values work well (plus I'm lazy and would rather look at birds than at a computer), but other presets are available along with user-customized settings.  Check out how much the image cleans up with a NoiseWare pass:

Screen Shot 2012-10-03 at 12.40.27 PM

Screen Shot 2012-10-03 at 12.40.55 PM

Screen Shot 2012-10-03 at 12.41.03 PM

Screen Shot 2012-10-03 at 12.41.13 PM

After processing for noise, I'll re-size the image.  Since this is for the web and/or email, I'll make it 14" wide @ 72 dpi.

Screen Shot 2012-10-03 at 12.44.26 PM

Screen Shot 2012-10-03 at 12.44.34 PM

Finally, I'll slightly adjust the levels so the bird looks like what I remember seeing:

Screen Shot 2012-10-03 at 12.47.56 PM

Screen Shot 2012-10-03 at 12.48.28 PM

And Shazzam- a slick pic of a neat bird encounter, much improved by about 1 minute of post-processing:

HETH_nest-8

 Here's one more case study of a high-ISO photo, this time of a Broad-tailed Hummingbird I shot in my back yard last August.  I really like the dramatic dark background, but that kind of backdrop is especially prone to showing sensor noise.  This image was shot at ISO 1800, with exposure compensation at -2/3 to avoid blowing out highlights on the sunlit bird.  Here's what it looks like out of the gate:

Screen Shot 2012-10-03 at 12.58.54 PM

Rotated and enlarged to 100%, the dark background looks pretty noisy:

Screen Shot 2012-10-03 at 1.00.30 PM

So I'll run it through NoiseWare to get this:

Screen Shot 2012-10-03 at 1.02.28 PM

A quick crop, re-size, level adjustment, & wee bit of sharpening leaves a pleasing image for the web or email:

Red-lining the ISO

by Bill Schmoker

Earlier this summer, I got a paradigm-altering email from my techno-savvy birding buddy Tom Wilberding. (I know- what a cool name for a birder!) Here's what he had to say:

Hi Willy,

I enjoyed your post on feeding buzzards. Glad you wear rubber gloves for that!

 Re camera tips and tricks, I sometimes miss shots going from bright light to dark shadows using Aperture Priority. The dark shots are blurry due to slow shutter speed. Lately I use Manual: speed set to 1/800 sec and aperture to f/5.6 or f/6.3. ISO? I set that on A for automatic. The result is that on the dark shots I end up with noise from the high ISO, but I use Lightroom noise reduction for that. Arthur Morris recommends this technique when on a boat shooting birds next to a dark cliff, then against the water, then against the sky—no time to adjust the camera. But I thought why not do this most all the time, as birds move so fast from ground to sky, dark to light?

 Here are some examples of my new point and shoot set up—most taken at 1/800 sec, f/5.6 or f/6.3. Automatic ISO jumps all over the place. It’s lazy and a no-brainer, which I like.  Goshawk Trail near Eldorado Canyon:  http://twilberding.zenfolio.com/p176924841/slideshow

When I wrapped my head around what he was saying I realized that using the Auto ISO in tough lighting conditions could really let me concentrate on the bird and not the camera.  I looked back on Arthur Morris's Birds as Art blog to see what he said about the technique and found a few entries including this one:  http://www.birdsasart-blog.com/2009/07/24/more-from-the-pangas/

A few weeks later I had the chance to test the technique, when I found a Hermit Thrush nest with two attending parents and a hungry brood of three chicks.  Conveniently, the nest was visible from a busy hiking trail and there was a clear lane to view it from across a creek without disturbing the nest.  I had never seen a Hermit Thrush nest before so that was cool, but the birds were foraging streamside in and out of sunlight and the nest itself was in deep shade about twenty feet up a spruce tree at Zapata Falls (Alamosa County, Colorado.)  I set my Nikon D3200 to shutter priority and chose 1/500 second to keep the 750mm-equivalent hand-held zoom (Sigma 50-500mm f/6.3, 1.5x crop factor) steady.  The camera sometimes pushed to ISO 4500, 5600 or even 6400(!!) to keep up in the shade but the results were pretty sweet.  My pics were certainly a lot better than I would have got just sticking to a "traditional" ISO like 400, cranking the aperture open, and trying to deal with the bad combination of slow shutter speeds and active birds.

Two take-aways for me:

1) Auto ISO combined with shutter priority or manual mode can be great in tough lighting conditions.

2) Don't fear high ISO values (maybe even crazy-high!) to keep your shutter speed in comfortable ranges, especially on newer-generation camera sensors that have much higher quality results at high ISO.

Next episode:  What if my high-ISO pics look noisy?

Enjoy- Bill Schmoker

eThoughts on eGrosbeaks

by Rick Wright

Mid-March, and Ted Floyd writes to ask whether I’d be interested in putting together a historical piece on Evening Grosbeaks for Birding. Before saying yes—writers always say yes—I looked at my calendar for the next several weeks: a Nebraska tour to conduct, a visitor from Germany to show around, a house closing and move to attend to, a lecture to give, three day-trips to lead for local birding groups, a new birding course to teach, a multi-day trip to run for Tucson Audubon, a long-awaited Hungarian vacation to enjoy...

Sure, why not?

Not that long ago, Ted’s request would have sent me into a dismayed panic: How on earth could I fit the library time in with everything else going on? Ah, but that’s precisely the trick. Nowadays, there’s almost no such thing as library time when you’re writing about birds. No dusty stacks, no unexplained gaps on the shelves, no towers of crumbling journal volumes studded with dollar bills and yesterday’s mail as bookmarks. Just a keyboard and a screen, and it’s all at hand.

Most birders know SORA, the University of New Mexico’s Searchable Ornithological Research Archive. A “keyword search”—how inscrutable a phrase like that would have been just a couple of decades ago!—for “Evening Grosbeak” will lead you to nearly 200 articles in more than a dozen of North America’s most important scientific journals of ornithology, from the earliest numbers of the Auk and Wilson Bulletin right into this century. Lots of the material there is technical, and I tune out as soon as I see a statistics formula (sorry, Ted); but especially in the earlier issues of the older publications, say up to the 1930s, these journals are chock-full of what would now be dismissed as “anecdote”—much of it in an elevated, even literary style that makes these stories of surprise sightings and bizarre experiences a blast to read.

Take Arthur H. Norton’s 1918 “Remarks” on the Evening Grosbeak in Maine and New England, a sort of spiritual forebear of my own essay but written in a prose the elegance of which is far beyond my reach:

Gifted with a striking richness of plumage, a phlegmatic disposition in which fear is but poorly developed, having a written history in which mystery, and romance have been involved, and having invaded a wide territory within a relatively short time, the Evening Grosbeak has received much attention wherever it has appeared.

A very rich source for this sort of thing, of course, is the series of Life Histories written, edited, or compiled by Arthur Cleveland Bent and his successors. Only a selection of these texts is online, so far as I know, and so it pays to have the paper copies on the shelf, too—happily, the Dover reprints of the whole series are widely available and cheap. The Evening Grosbeak account is one of the entries available in digital format, and reading it this time I was struck by the hands-on familiarity so evident in the author’s approach to the subject. In the old days, I might have jotted the author’s name down and forgotten about it, but thanks to Google, I was able to look her up immediately. Doris Huestis Speirs (1894–1989) turns out to be a fascinating personage, even if she doesn’t have a Wikipedia entry (yet). Her contributions to ornithology are commemorated in the Speirs Award, the most prestigious award granted by the Society of Canadian Ornithologists–Société des ornithologistes du Canada. She was a friend and champion of Margaret Morse Nice, and a minor artist with major connections to the so-called Group of Seven. Her interest in Evening Grosbeaks started while she was living in Ontario in the 1930s, and ornithology displaced painting for her when she and her husband moved to Urbana, where he took his Ph.D.

It’s always a good day when you get to know someone interesting, even someone from another century.

No matter how extensive the e-resources out there, they always leave some questions unanswered. The materials I collected from the 1960s contain several mentions of DDT and its effects on the Evening Grosbeak, especially in eastern Canada; have a look, for example, at this article or at this one. The species account in Birds of North American Online simply notes “no apparent direct effect,” but I would be very much interested in learning more about what birders and ornithologists thought at the time and what, if anything, was done to stop spraying in areas frequented by grosbeaks; we tell the story of DDT largely in terms of raptors, but here’s a chapter waiting to be added.

When I set out to write this essay, I decided to start at the beginning: with the first scientific description of the species. Locating formal descriptions used to be fraught with difficulties: Few were the libraries that housed all of the incredibly disparate sources in which the older descriptions were published, and even then many were held in closed collections, with access limited to inconvenient hours of the day. No longer. Welcome, Biodiversity Heritage Library! This spectacular resource is my first port of call when I suspect that I have a difficult citation. In this case, the AOU Check-list told me that I was looking for something possibly quite obscure: The citation there reads “Fringilla  vespertina W. Cooper, 1825, Ann. Lyc. Nat. Hist. N.Y.  1: 220. (Sault Ste. Marie, near Lake Superior [Michigan].)” Challenging—especially since I wasn’t sure what language the journal title was in, each element being susceptible of resolution in English or Latin or French or, what do I know, Romanian. Because the type locality was given in English, though, I guessed that the journal must be something like the “Annals of the Lyceum of Natural History of New York.” Good guess. An easy thing, then, to click on the cited page and read Cooper’s very words from nearly two centuries away.

The original descriptions of North American—and other—birds offer hours of interesting, sometimes amusing reading. Grazing one’s way through them used to be simply impossible, but today, there’s nothing easier than having a checklist open in one “tab” and BHL in another.

The Biodiversity Heritage Library is also great for finding old illustrations. BHL has a flickr page with some tens of thousands of bird images, and of course the books themselves are full of pictures. The Internet Archive, though not as extensive or as well arranged as BHL, also hides treasures. Take a look at Lesson’s “Bonaparte Grosbeak

Bonaparte Grosbeak, Lesson

from his riotously miscellaneous Illustrations de zoologie.

I’d wanted to include that image in the Birding article, but we opted instead for an Audubon plate. The one we chose, number 424 in the original double elephant edition, is interesting for a number of reasons.

12-4-09-03 [Audubon print from University of Pittsburgh]

Not only does it illustrate the contemporary tendency to see the Evening Grosbeak as a decidedly western bird, but this plate also purports to show for the first time the juvenile male of that species. In fact, though, as Benjamin Shaub pointed out in The Wilson Bulletin in 1964, Audubon’s label is “among the great errors to be found in Audubon’s superb paintings. It is, indeed, quite evident that he had never seen a juvenile male Evening Grosbeak, and probably none were described prior to the account by Magee” published in 1934. Another splendid example of how long it has taken ornithology to figure this mysterious bird out.

The Audubon plate harbors other mysteries. As our caption laconically put it, “The identities of the other birds are not as clear.” How many did you figure out? The other species depicted here on number 424 are 1. Lazuli Bunting, “Lazuli Finch”; 2. House Finch, “Crimson-necked Bull-finch”; 3. Gray-crowned Rosy-Finch, “Gray-crowned Linnet”; 4. Brown-headed Cowbird, “Cow-pen Bird”; and 7. Sooty Fox Sparrow, “Brown Longspur.”

Three of the images from this plate were used in the construction of the “Composite Plates” with which Audubon supplemented the original edition of his Birds of America. The female Lazuli Bunting was added to the original Plate 398 to accompany the male, and both Evening Grosbeaks were added to the original Plate 373, which had been drafted with only a single male bird.

The painting by Allan Brooks that accompanies my essay breaks the Evening Grosbeak out of its exclusively western context to make it one of a decidedly miscellaneous group. The White-collared Seedeater is a tropical south Texas specialty, and the “gaudy” Painted Bunting is nearly as resolutely southern in distribution; few are the birders who have seen either of those species in the company of an Evening Grosbeak, and I’d be willing to wager that no one has ever seen all three in the same day. The Dickcissel—here labeled the “masquerader,” I suppose for its distant resemblance to a meadowlark—is a more interesting companion for the grosbeaks: Just as the Evening Grosbeak had moved east, to “ramble in winter over all northern States,” the Dickcissel had retreated west, forsaking “the eastern seabird for interior States some 65 years ago.” The mind dwells on imagined flocks of grosbeaks and Dickcissels, crossing paths somewhere in eastern Ohio as the one flees the East and the other conquers it.

Even more piquant is the fact that 20 years before Brooks’s painting was published, Joseph Grinnell had described a new subspecies of the Evening Grosbeak. He gave the bird the English name “British Columbia Evening Grosbeak,” and assigned it the subspecific epithet—get this—brooksi, “in recognition of Allan Brooks’s contributions to northwestern ornithology.”

It all makes me happy I said yes.
