Selayar Whistler

A mostly terrestrial and chunky light brown bird of the north and central Chaco, from central Argentina to Western Paraguay and extreme SE Bolivia. Distinguished from Rufous Hornero by crest, from Lark-like Brushrunner by plain plumage, and from Cachalotes by dull plumage, smaller bill and size, and dark iris. Generally found in woodland, thorn scrub, and adjacent habitats. Builds large, open mud domed nests on exposed branches or power poles.

Small tan flycatcher of river beaches; terrestrial, or perches on low shrubs. Tan above, lighter whitish below, with a black tail with white outer tail feathers. Overlaps with the similar and often more common Drab Water Tyrant. Compared to that species, Little Ground-Tyrant has lighter underparts, no facial pattern (unlike the black eye line and pale eyebrow of Drab Water Tyrant) and white outer tail feathers contrasting with black inner tail feathers (as opposed to uniformly brown). They often flush and move in low flight along river banks, exposing their diagnostic tail patterns. Prefers wide, open beaches and mudflats along rivers to steep river banks. Known to wander when not breeding, when it can be found in a variety of open habitats.

Magnificent dark antshrike of mature upland rainforest. Has a large head with a crest and strongly hooked bill. Males are slaty gray with fine black barring; females are tawny orange with fine black barring. Larger than most other antshrikes and antbirds in its range. Forages singly or in pairs in open understory, and seems to be somewhat rare throughout its range. Its song is a gradually rising series of low whistles given at a steady pace.
