Black-backed Grosbeak Pheucticus aureoventris

Uncommon in the Andes from western Venezuela to Argentina. Male is black above with a yellow belly and prominent white patches on the wings. Most populations have an entirely black head and chest, but birds in southern Colombia and Ecuador have yellow up the throat. Females are similar to males, but are duller brownish instead of black with more yellowish mottling above. Both sexes have huge bill. Occurs in scrubby woodlands, forest edge, and gardens from around 500 to 3,200 m. Often found in pairs that perch conspicuously.
