Blue-fronted Redstart

Uncommon swift found along the east slope of the Andes from central Bolivia to northwestern Argentina. Uniform sooty brown, lacking any strong plumage characteristics. Easily confused with Sick’s Swift, but is larger with longer wings, giving it a sleeker and more aerodynamic appearance; also lacks a pale throat, though this is often hard to see clearly. In central Bolivia it could be mistaken for Chestnut-collared Swift (some of which lack a chestnut collar), but wings are slightly narrower at the base. Usually seen in flocks of a few birds up to 20 or more that circle over humid forest.

Medium-sized thornbird with a long tail. Note orange eyes and rufous forehead, throat, and tail while the body is largely brown. Similar to Orange-breasted Thornbird, but has orange rather than dark eyes. Found in pairs on the edge of humid forests, usually near marshes and water bodies where it builds huge stick nests. The song is loud and nasal, usually delivered as a duet.

A fairly large pigeon of lowland and foothill rainforest interior. Pale pinkish head, orange underparts, metallic emerald green wings and back, and a purple rump. It is usually solitary, difficult to see and does not usually fly above the canopy. Similar to Rufescent Imperial Pigeon, but Purple-tailed is found at lower elevations and has an obvious pale gray tail band. Call, two introductory “tuk-tuk” notes followed by a long, rather out of tune, rising then falling “ooo-woo-ooo”
