Rüppell's Weaver

Plain brown flycatcher with a large-eyed appearance. Note bright white eyering and unmarked throat and underparts. Appears shorter- and plainer-winged than other similar brownish flycatchers. Favors broadleaf forests; also found in more open habitats on migration and wintering grounds. Sallies from exposed perches; cocks tail and flicks wings when perched. Song comprises high buzzy trilling and whistles. Calls include dry rattling and chittering.

Large, chunky antbird. Male is uniformly sooty black with pale blue skin around the eye. Female is warm dark brown above and gray below, and also has blue skin around the eye. Occurs in pairs in the understory of mature lowland forest in the Amazon basin, east of the Andes. Can be seen in the vicinity of army ant swarms. Look for the tail being pumped down and raised slowly up.

A common prinia with drab gray-brown plumage that varies in tone across its range. Note the pale, wide eyebrow and the long tail that appears as if it is loosely attached to the body. Breeding birds have a black bill and a shorter tail. Common in various habitats, especially farms and wetlands, but avoids woodlands with a canopy. A somewhat bold species, it often skulks in the undergrowth but sings from exposed perches. The song is a repeated series of insectlike trills. Calls include various buzzing and clinking notes. Also produces snapping sounds with its wings.
