Rufous-sided Honeyeater

Very rare antwren, unmistakable in its tiny range, likely now restricted to one complex of humid forest fragments in the Brazilian state of Alagoas. Males are gray with a blackish throat and females are cinnamon-colored. Forages in the understory and middle levels of the forest, usually accompanying remnant mixed-species flocks. The song is a high sharp series of whistles.

Large spiderhunter with thick yellow eyerings, a yellow ear tuft, and a long decurved bill. Yellow eyering and cheek splotch serve to distinguish it from most other spiderhunters. Yellow-eared Spiderhunter is very similar but noticeably smaller, with a narrower eyering, faint streaking on the breast (versus plain), and a slightly longer, more slender bill. Found in lowland and foothill forests, where it forages actively in the upper levels. Calls include harsh chip notes.

Impressive roadrunner-like cuckoo found in Amazonian rainforest. Large and long-tailed, with a red bill tipped with yellow and a red face. Upperparts are bronzy green with chestnut wings and a black cap, and underparts are mostly gray with a black breast band (indistinct on some birds) and faint barring on the throat. Distinguished from Rufous-vented Ground-Cuckoo by Red-billed’s mostly red bill, red face, completely black crown, and chestnut wings. Rarely encountered and poorly known, but like other ground-cuckoos it is terrestrial and most likely to be encountered when following swarms of army ants. Song is a very low, rising “who?” that is repeated every few seconds; also gives loud bill snaps.
