The yellow-thighed finch (Pselliophorus tibialis) is a passerine bird which is endemic to the highlands of Costa Rica and western Panama. Despite its name, it is not a true finch, but rather a member of the large Emberizidae family, which also includes buntings, American sparrows, juncos and towhees. This is a common bird in wet mountain forests, second growth, bamboo clumps, scrubby pasture and bushy clearings from 1700 m altitude to the timberline. When not breeding, it can descend to 1200 m on the Caribbean slopes.
