Cassia Crossbill: Medium finch, male with red-orange body, brighter red rump and crown, and gray-brown on face, wings, and tail. Female has olive plumage. Bill is dark and crossed at tip. The tail is notched. Legs and feet are gray-black. Eats lodgepole pine seeds, insects and caterpillars. Forages by picking seeds from the cone while perched at any height, even on the ground. Swift bounding flight, alternates rapid wing beats with wings pulled briefly to sides.

Vocalization

Cassia Crossbill: Song is a buzzy "chup-chup-chup-chup, zee-zee-zee-zee"; call is a "chip, chip".
