Here are some things I’ve learned from the Peterson Reference Guide to Owls of North America and the Caribbean by Scott Weidensaul: The Burrowing Owl is the only North American owl species where the male is larger than the female, albeit, only slightly larger. And the term is ‘non-reversed size dimorphism.’).

An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell. Similarly, descriptions of species repeated across volumes do not lose their accuracy with each publication. Other species are splits and lumped and have had their names changed. Why are these issues?

I recently asked whether Puerto Rico should be part of the American Birding Association’s ABA Area. I will suggest an answer to the question: this post makes the argument that both Puerto Rico and the U.S. Now that Hawaii is in the ABA Area , the next additions should be Puerto Rico and the U.S.
