Blog Birding #333

We certainly have a good idea of what an eclipse looks like, but do we know what one *sounds* like? Cornell researchers tried to find out in 1963, Marc Devokaitis at All About Birds tells the tale.

“The eclipse does not influence many of the factors which affect bird song such as time of year and the physiological condition of the bird,” he wrote in the 1963 issue of The Living Bird. “It is also probable that the sudden interruption of an established diurnal routine is more confusing to some species or individuals than others. All these possibilities for variation in cause and effect…tend to keep the value of any observation a strictly local affair.”

The heat of summer is upon us, and birds are having to deal with what is among the most difficult times of the year. How do they do it? David Sibley lays out their strategies at Birdwatching.

Birds do not sweat, so the only option for evaporative cooling is to open their bill and flutter their throat to allow moisture to evaporate out of the mouth. Other options for cooling off include reducing insulation by compressing feathers tightly against the body, which makes the legs look longer, and holding the wings away from the body to expose bare skin.

For World Shorebirds Day, check out the work done on endangered Piping Plovers by Alician Fortin and others on the Ontario Great Lakes at the World Shorebirds Day Blog.

Generally eggs are laid in May, and occasionally in June if the parents lose their first clutch of eggs. Piping Plovers lay their eggs every other day, and very consistently lay four eggs in their first clutch. When the first egg is found on Sauble Beach, a mini-exclosure is put up by the Ontario Ministry of Natural Resources and Forestry (OMNRF), which is a rectangular wire cage above the eggs to protect them from predators such as Raccoons, Ring-Billed Gulls, and American Crows. A perimeter with a 50m radius (more or less) is roped off around the exclosure to minimize human disturbance.

The proposed Santa Ana NWR border wall is an ongoing issue. AT 10,000 Birds, Jason Crotty looks at the oft asked question of whether environmental laws might be able to stop it.

Several pieces of legislation have empowered the Secretary of Homeland Security to waive numerous laws, including all environmental laws, when he or she determines that doing so is necessary to secure the border.  That decision is discretionary with the Secretary and is essentially unreviewable.  All challenges in court have been unsuccessful and current and/or future challenges face daunting odds.

At SparrowWorks, in this season of flowers and young birdsRichard Gregson shares the going on in his garden .

Canna Lilies are now in bloom (that pleases the Hummingbirds), most of the phlox flowers are open, The PG Hydrangea pannicles that were white when we left have turned rosy-pink, there are flowering Rudbeckia/Black-eyed Susans everywhere … and as soon as the bird feeders were refilled they were fallen on by five juvenile Purple Finches.
