Viridian Dacnis

Often draws attention to its presence by its song: an ascending sequence of “kwa” notes, similar to Green-backed Trogon, but faster. Two subspecies occur in Brazil, Paraguay, and northeastern Argentina with limited geographical overlap that vary in the color of the breast and eyering; the southern one has a red belly and eyering, while the northern one has a yellow belly and eyering. The males of both subspecies have a violet-blue head and breast, a green back, and a white undertail. Females have a dull gray breast and the undertail is gray with white tips. Found in the middle to upper levels of forests and woodlands.

Small distinctive duck. Males have a pinkish breast that is spotted in black with a rich chestnut wing and a metallic green patch on the flight feathers. Note the blue bill. Females have a striking brown-and-white face pattern, and are mostly brown above and mottled or banded brown below. In flight shows dark wings with white-and-green bands. Occurs in marshes and swamps with abundant vegetation; can be even seen perched on fences or low trees.

A distinctive medium-sized yellow bird with a black head and breast, black flight feathers, and a red bill. In flight, the black band towards the tail tip is visible. Juvenile is duller overall with a white streaked throat and a darker bill. Often feeds on fruiting trees with a preference for figs in wooded gardens, groves, and open forests. The song is rich, fluty, and mellow. Calls include raspy, nasal notes that can sound like a croak.
