Chestnut-capped Brushfinch

The chestnut-capped brushfinch is 16 to 19.5 cm (6.3 to 7.7 in) long and weighs about 32 to 47 g (1.1 to 1.7 oz). It is one of the larger brushfinches. The sexes have the same plumage. Adults of the nominate subspecies A. b. brunneinucha have a wide black mask from their forehead and forecrown down to below the gape and back to the side of the neck. Within it they have a small white spot above the lores. Their crown and nape are chestnut with a thin yellowish tawny supercilium separating it from the top of the mask. Voice: One description of the chestnut-capped brushfinch's song is "a jumble of high-pitched, slurred whistles and staccato notes, peetee-zeer, peetee-súueet". Another is "a fairly slow, high-pitched series of sharp whistles: tseeee-tseeu-pseee-tzzzeeee". A third is "a high, sibilant series of thin whistles...for example: see-swee-sew-see-swee-SEER".
