There was a time when I thought each bird species had its own individual song. Then I found out that there was this vocalization called a ‘call,’ so I thought each bird species had its own individual song (but just the males) and individual call. Bird communication is a complex and evolving science. How do they know?

Southeastern Arizona is unusual, precisely because its species mix is as much Mexican as it is American.

I stopped at the Red Crossbill , realizing that the species indeed “occupies an immense range, including North America, Eurasia, and northern Africa” (HBW) – including Baxi forest, China.

The species was named after John P. I suspect there is little opposition to changing the names of species with particularly sordid namesakes.
