Mystery Bird: Plain Chachalaca, Ortalis vetula

I'm calling that a plain chachalaca. I realize that in other parts of the Americas the ID would be a bit trickier, but north of the Rio Grande I think it's probably safe to make the call on the basis of its "chachalaca-ness" alone. But it does match the illustration in Sibley pretty well, including the "conspicuous red gular-stripe when displaying".

I agree John, a Plain Chachalaca, Ortalis vetula from the family Cracidae (including Gunas and Currasows): greyish head and neck with a dull olive-brown body and wings; brown iris and black beak; orbital skin (and legs) grey; red ptach of skin on throat... initially I was a little concerned about the darkness of the breast, having seen a number with much lighter coloring but because there are no other chachalacas in range (there are at least another dozen species throughout Central and South America), there must be some variation within the species

According to the Integrated Taxonomic Information System (the taxonomic backbone to the Encyclopedia of Life) there are five subspecies of Ortalis vetula: deschauenseei, intermedia, mcalli, pallidiventris, and the nominate subspecies vetula.

According to the Internet Bird Collection, ranges and alternate names for each subspecies show that the nominate O.v. vetula is endemic to eastern & southern Mexico, Belize, eastern Guatemala, Honduras, western Nicaragua and northwest Costa Rica and is called the Common, Mexican, or Eastern Chachalaca- the most northern subspecies, from northern Veracruz and northeast Mexico up to southern Texas is O.v. mccalli, or the Northern Chachalaca, so I am qualifying my answer as:

Ortalis vetula mccalli, the Northern Chachalaca

Does that bird remind anyone else of Sam the Eagle from The Muppet Show?

In Brazil caled aracuã.
