Brown Inca

The brown inca is about 11 to 13 cm (4.3 to 5.1 in) long. Males weigh about 7.0 g (0.25 oz) and females about 6.5 g (0.23 oz). Both sexes have a long, straight, black bill and a white spot behind the eye. Adult males' upperparts are reddish bronze with a greenish olive lower back and a bronzy forked tail. Their underparts are mostly dull brown with an amethyst gorget and a white patch on each side of the breast. Adult females are essentially the same as males but for a longer bill, a smaller gorget, and a less forked tail. Immatures resemble the adult female. Voice: What is thought to be the brown inca's song is "a repeated phrase comprising three notes, 'tsip-tzreeew-tzrew'". It has a variety of calls such as "tsit" and "tsi-tsit" notes and a "tsitsitsitsitsit…tsitsitsi...tsitsitsit..." series. In flight it utters "a short rattle 'trrr', short twitters... a high-pitched 'tzree...tzee...tzee...tzee'."
