10,000 Birds

APRIL 2, 2019

I like sparrows. I like observing them, reading about them, grappling with species and subspecies identification, and even—on a good day—talking about sparrow taxonomy. The book does not include House Sparrow, an Old World sparrow that belongs to a completely different bird family. Scope of Book. Mexico border.

Their migration is quite fast compared to many other larger birds – in one study , several birds flew 4000 km within 5–7 days while one individual even flew 5600 km non-stop. That includes breeding birds, as indicated by the presence of some rather cute chicks ( video ). Also as video. Bye, bye, Lesser Coucal.

Proposal 2013-A-3 recommends adopting that split on the basis of a 2009 study (I wrote about it back in the day here ). Sage Sparrow split. Proposal 2013-A-7 would split the Sage Sparrow ( Amphispiza belli ) into two species: Great Basin Sage Sparrow ( A. nevadensis ) and California Sage Sparrow ( A. acuflavida ).

In my case, I had to format my excel sheet just so, a considerable task because when I dabbled in Birdstack (gone, alas, but not forgotten) I adopted its formatting as well as the more fluid International Ornithological Congress (IOC) taxonomy , both of which were inimical to that of eBird. Importing locations is even more ridiculous.
