Here are a few other things regular readers of this site may be familiar with: The bird science journal “The Condor,” the Museum of Vertebrate Zoology at UC Berkeley, the concept of “niche,” and the system for making field observations of species known as the “Grinnell System.” PNAS August 6, 2018.

Scientists were largely limited to studies birds in breeding colonies, at least those we knew about and that were accessible (and, if you think that’s a complete list, you haven’t read the news that came out this week about a new colony of Adélie penguins found in the Danger Islands, Antarctica). Technology to the rescue!

The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. Clearly, this is an under-birded country. .

In the case of the Hawaiian Goose ( Branta sandvicensis ), the public notice was published in the Federal Register on April 2, 2018. It contains numerous citations to the literature, as the process must be based on the best available science. Also, research filled in many knowledge gaps and informed conservation efforts.

For quite a few birders visiting Wuyuan, the main reason is to see the Blue-crowned Laughingthrush. The Grey-sided Scimitar Babbler looks like it is constantly a bit confused about the status of this world.

Describing gull plumage is a combination of science, graphic art, and visual metaphor. Distribution maps, ranging in size from one-eight to one-half of a page, indicate breeding and non-breeding habitats and trace migration routes. Princeton University Press, 2018.

A paper titled “Crested Goshawk Accipiter trivirgatus may adapt well to life in urban areas across its range in Asia” already made the same observation in 2018. The Little Grebe is of course a very common bird that can still surprise by its beauty in its breeding plumage. But it is all for science, I hear them say.
