Tucuman Mountain Finch

An unusual small, chunky flycatcher. At a distance, looks entirely dark, but a good view reveals a slightly paler throat and a dark undertail with paler fringes. Has long, pointed wings and looks a bit like a swallow in flight. Found in rainforest and gallery forest, where it perches up on dead trees, especially at the forest edge and around clearings. Often in small groups. Similar to Sooty Flycatcher, but there is little or no overlap in range, and Ussher’s is separated by its darker underparts. Easily separated from other flycatchers by very dark plumage and unusual habits. Not very vocal, but does give a quiet, squeaky song. 

A large grayish-brown duck with a diagnostic yellow-tipped black bill and a red spot at the base of the bill (missing in certain subspecies). In flight, note the green panel in the wing that is bordered in white. Often seen in small groups dabbling or tipping up in shallow water or walking on marshy land at the edge of freshwater lakes or in cultivated fields. Usually not seen associating with other species. Similar to Eastern Spot-billed Duck, but note green wing panel, lack of a distinct dark "moustache", and overall warmer tan coloration.

Utterly unmistakable inhabitant of waterside and riverine lowland evergreen forests, mangroves, and plantations. Midnight black with long white slashes on each wing, wine-red underparts, and a black chinstrap. Bulbous bill is glowingly powder-blue with warm tinges of orange and greenish-yellow. During the breeding season, the pendulous nests of this species can be quite obvious, hanging over forested waterways. Voice is nasal and generally unpleasant-sounding, consisting of odd low mechanical rasps.
