YELLOW GROSBEAK

Yellow Grosbeak, Pheucticus chrysopeplus

In the list, one of the prettiest species is the Yellow Grosbeak sketched above, just as I saw him perched next to a bromeliad. This bird extends from western Mexico into Guatemala, and similar species (or maybe just subspecies...) are found as far south as Peru. Yellow Grosbeaks are found along forest borders, cut-over breaks, brushy woods and wooded canyons exactly like this in mountains and foothills. It's a little similar to North America's Evening Grosbeak, but that species has a much darker head and the white on its wing is much more extensive.
