Viridian Dacnis

The viridian dacnis is 9.5 to 10.5 cm (3.7 to 4.1 in) long. It has a short, conical, sharply pointed bill. The species is sexually dimorphic. Adult males have a green head with dusky lores. Their mantle has a triangular black patch. Their lower back and rump are greenish blue and their uppertail coverts blue. Their wing's inner coverts and flight feathers are bright olive green with blue edges and the outer coverts and primaries are black. Their tail is dusky. The green of the head becomes greenish blue on the throat, breast, belly, and undertail coverts. Adult females have a green head, a pale olive green nape, back, and rump, and blue-tinged olive uppertail coverts. Their wings are mostly olive green with greenish-edged outer primaries. Their tail is dusky. Their throat and underparts are mostly pale yellowish olive with a pale buff center to the belly and yellow undertail coverts. Both sexes have a yellow iris, a black bill, and gray legs and feet.

The viridian dacnis straddles the border between Panama and Colombia. In the former it is found in far eastern Darién Province. In Colombia it is found around the Gulf of Urabá in northern Chocó, northern Antioquia, and western Córdoba departments. It inhabits the canopy and edges of humid tropical evergreen forest. In elevation it ranges from sea level to 600 m (2,000 ft).

The viridian dacnis' diet and foraging behavior have not been studied. They are assumed to be similar to those of other Dacnis species, for example see here.
