Chestnut-capped Brushfinch
Arremon brunneinucha
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".

Pectoral Sparrow
Arremon taciturnus
The pectoral sparrow is sexually dimorphic, and, as the name implies, sparrow-sized, at 15 cm (5.9 in) in length and 24 g (0.85 oz) in weight. Its upperparts are pale green, becoming yellow near the bend of the wing. The head is black, with white on its throat and as stripes on its crown. Its underparts are white in males and creamy in females, with males also having a broad black band going across its breast (a pectoral band). The beak is also black, roughly 14–15 mm (0.55–0.59 in) long for both males and females. Tails are 58–60 and 64–67 mm (2.3–2.4 and 2.5–2. Voice: The song of the pectoral sparrow is a high-pitched buzz, consisting of very short tzik notes (initial tzik note may be slightly faster, and lower in pitch.) and usually followed by 2-4 longer, almost identical tzzzzzz notes. The entire song lasts for 2–3 seconds, at a pitch of 8 kilohertz.
