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?

It’s a decidedly different direction for the author of Kingbird Highway (1997), Kaufman Field Guide to Birds of North America (2005), and A Season on the Wind: Inside the World of Spring Migration (2019), to cite just three of his books, and one that I thoroughly enjoyed, underlined with energy, and am still thinking about.

What are the best field guides for birds in North America? Birders often venture into various habitats, such as forests, wetlands, grasslands, or coastal areas, to encounter different bird species. The primary objective of birding is to identify bird species based on their physical characteristics, behavior, and vocalizations.

All sorts of exotic and beautiful species may be seen. This would sound attractive even to me, except for one fact: almost all of those exotic and beautiful species are common down here in central Mexico. Southeastern Arizona is unusual, precisely because its species mix is as much Mexican as it is American.

An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell.
