Short-tailed Antthrush

Very small, finchlike bird of grassy and weedy areas in tropical lowlands, especially in marshy areas. Often in flocks, mixing readily with slightly larger White-collared Seedeater. Breeding male (only in spring–summer) is striking: slaty bluish above and rusty below with a rusty rump. Nonbreeding male, female, and immature are much plainer: buffy brown overall, paler below, with distinct paler wing edgings (unlike plain-winged White-collared Seedeaters in west Mexico), and distinct orangey tones to the bill (bill dusky on White-collared).

Tiny and strikingly-plumaged flycatcher with a long tail and distinct face pattern. Has a gray crown, a broad white eyebrow with a vertical black crescent running behind the eyes. The body is olive-yellow above and bright yellow below. An uncommon and threatened inhabitant of the middle levels of montane forests and forest edges including Araucaria forests. The song is a high-pitched trill.

Nondescript manakin that may be mistaken for a flycatcher. Has an olive-green back, a grayish throat, and yellowish underparts. The yellow crown patch is typically concealed. Found in the interior of humid forests, occasionally venturing to the edges. A common call is a startled “yo-dee-wo-dee”. The similar Serra do Mar Tyrant-Manakin has a conspicuous yellow crown patch, occupies different edge habitats, and has a more complex song.
