Cassia Crossbill Loxia sinesciuris

Stocky, large-headed finch with unique crossed bill used to pry seeds out of lodgepole pine cones. Similar to Red Crossbill, best separated by voice, specifically the flight calls given in flight, a comparatively lower frequency, dry "dip-dip-dip". Endemic to Albion Mountains and South Hills of southern Idaho. Males are dull red or orange overall with gray or brown highlights. Females are dull olive-yellow. Immatures are streakier than adults. Sedentary, unlike most other crossbills. Often in small flocks. Rarely visits feeders.
