eBird makes novice birders into community scientists, as Mukta Patil explores at Sierra. 

With this information, the team at Cornell is able to gather information about things like bird distribution, population, and habitat use. “We’re interested in understanding what’s happening with a biological system,” Wood says. “And in order to do that, we also need to understand what’s happening with the birdwatcher as part of the observation process.”

Saltmarsh Sparrows are in bad way due to sea level rise and, according to Purbita Saha at Audubon, federal protections does not appear to be coming any time soon.

The four-year window also has other limitations. For one, Elphick says, it doesn’t give USFWS enough time to weigh outcomes from field testing and pilot projects. “Cutting down trees to see if marshes will migrate inland, raising entire nesting sites—you don’t collect immediate results,” he explains. “Maybe we can wait another decade for that insight, but Saltmarsh Sparrows could be extinct in a decade and a half.”

At BirdWatching Daily, the report of a massive Tufted Puffin die-off in the Bering Sea that is likely the result of rapid climate change in the Arctic.

Tufted Puffins breeding in the Bering Sea, off the coast of Alaska, feed on fish and marine invertebrates, which in turn feed on ocean plankton. Elevation of sea temperatures has led to major changes in ocean ecosystems, and has been linked to previous mass mortality events in marine birds. Beginning in 2014, increased atmospheric temperatures and decreased winter sea ice led to declines in energy-rich prey species in the Bering Sea, as well as a shift of some species more northward, diminishing puffin food resources in the southern portion of the sea.

At MocosocoBirds, Jonathan Klizas shares the joy of finding Mourning and Kentucky Warblers in New Jersey.

Seeing or hearing one Mourning Warbler in spring migration is a special treat. May 2019 is becoming an embarrassment of riches in Morris and Somerset Counties. One, two, and maybe more, Mourning Warblers are reported from Troy Meadows since May 22 through today, May 30. One, in particular, has frequented the same brushy location since May 22 through May 30.

At The AOS News Blog a summary of a study that found that adding UV lights to power line poles cuts crane mortality by collision by a significant amount.

Crane species are declining around the world, and lethal collisions with power lines are an ongoing threat to many crane populations. Current techniques for marking power lines and making them more visible to cranes aren’t always effective, but new research published in The Condor: Ornithological Applications shows that adding UV lights—to which many birds are sensitive—can cut crane collisions with power lines by 98%.
