Buff-banded Tyrannulet
Mecocerculus hellmayri
Small flycatcher of the subcanopy of humid montane forest at middle elevation of the eastern slope of the Andes from NE Argentina to S Peru. More often heard than seen. Song two high, flat “see” notes, easily confused with Purple-throated Euphonia, but higher and thinner. Often in mixed species flocks. Note greenish wingbars, pale gray cap, and short tail.

Keel-billed Toucan
Ramphastos sulfuratus
Large unmistakable toucan with a huge, rainbow-colored bill. Often seen in pairs, but not usually in groups like aracaris. Flies with a few flaps followed by a swooping glide, sometimes high over the forest canopy, and looks like a ‘flying banana.’ Heard more often than seen: ‘song’ is a far-carrying, frog-like croak, repeated steadily. Despite its large size and bright colors, can be difficult to see in leafy canopy, where it moves deliberately in search of food.

Cobb's Wren
Troglodytes cobbi
Endemic to the Falkland Islands, where it is found in seashore areas and offshore islets, typically in association with tussac grass. Often forages on rocky beaches, picking at food items washed up by the tide. Somewhat similar House Wren has wandered to the Falklands before, but note present species’ gray-brown head and neck, lack of a prominent eyering, and longer darker bill. Can be tame and confiding, allowing close approach. Rattling song, somewhat similar to that of House Wren, can be given from an exposed perch or deep in cover. Calls include nasal mews and harsh, dry churrs and rattles.

Slaty-tailed Trogon
Trogon massena
Large, red-bellied trogon of humid tropical lowlands. Favors rainforest interior, but also found at edges and around clearings, mainly perched quietly and in an upright position at middle to upper levels in larger trees. Lack of white band above the red belly and entirely dark gray undertail (or with a few fine white bars at the sides on immatures) separate Slaty-tailed from other red-bellied trogons. On males also note the stout orange bill and orange eyering. Digs its nest in arboreal termite nests.
