Osborn, a passionate field biologist who participates to the core of her being three re-introduction projects aimed at saving three very different, endangered species: Peregrine Falcon, Hawaiian Crow (‘Alala)*, and California Condor. Well-researched and footnoted, these sections never feel disconnected from the more personal sections.

So, while waiting for evolution to produce new birds for our life lists is inadvisable, we sometimes catch a break and every few years get a new species or two when some genetic research or study of breeding distribution presents enough evidence to split what was once considered a single species into a few new ones.

Several years ago, I read about the enormous colonies of breeding birds in the Northwestern Hawaiian Islands and I did some research to satisfy my curiosity. ( Google Scholar is an excellent resource and free full-text PDFs can be located for many papers, particularly when research is taxpayer-funded. It is all business.

Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946. The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California.

Now that Hawaii is in the ABA Area , the next additions should be Puerto Rico and the U.S. The Hawaii vote made it clear that that the ABA Area is about political borders, not geographical or ecological ones, and the two Caribbean territories have long been part of the United States. But even with Hawaii, there are many U.S.

The Latin species name of the Kalij Pheasant is leucomelanos , meaning “white” (leukos) and “black” (melanos, both Greek words). A bit surprisingly (at least to me), the Kalij Pheasant has been introduced and established as a gamebird in Hawaii. thesis – as she did – is a bit much though. New Jersey.

These characteristics (well, not the pagoda, I guess) make it an interesting location for birdwatching in Shanghai, with some species that are difficult to find elsewhere. Strangely, the eBird entry for this bird talks in detail about its distribution on Hawaii, even though it has only been introduced there. I swear it wasn’t me.

Severe weather can stress birds and even influence the coloration of their feathers , new research finds. Researchers have figured out where the thought-to-be-extinct Bryan’s Shearwater is roosting. Research that’s sure to peeve anyone who’s struggled to list both a Common Redpoll and a Hoary Redpoll.

Decades later, Richard Pough’s Audubon Bird Guide, Eastern Land Birds (I happily own the 1948 edition) included nest and egg descriptions for each species as well. And photographs of feathers in the species accounts, which surprised me. Text retrieved from the Hathitrust Digital Library. The first is accomplished well.
