Can you identify the species, age, and sex of the South Texas falcons in this mystery quiz plate from The Crossley ID Guide: Raptors? Here’s some advice from the authors:
Focus on size, shape, and broad patterns of plumage. Kestrels are slim and rufous overall, whereas Merlins are compact and dark. Aplomado is elegant, long-winged, and dark-backed, with a striking head pattern. Peregrine is grayish and heavily built, looking much bigger and sturdier than any of the other falcons on this plate.
