Pinzón de anteojos Callacanthis burtoni

Bizarre and unique-looking finch. Note the lumpy diagnostic patch of bright color around the eye and forehead: red in males, yellow in females. Brownish overall with white wingbars; underparts are rosy-tinged in males. Breeds in mountainous and hilly forests and winters at lower elevations in clearings and forest edge. Moves in pairs and small to medium-sized flocks, often foraging out in the open or perched up on top of trees. Typical song descending and fluid, with a sharp uptick towards the end; also gives fluty and chipping notes.
