Northern White-faced Owl

Endangered, small black-and-white shearwater, endemic to Mexico. Found around Socorro Island mainly from November to May, and rarely offshore between Jalisco and Oaxaca. It is usually found with feeding flocks of other shearwaters, boobies, and terns. Flight is fast and strong, wheeling fairly high in strong winds. Blackish above and white below with blackish undertail coverts, fairly long tail, and white patches or saddlebags that wrap up around the base of the tail. Similar species: Black-vented Shearwater is dark brownish above without the strong black cap of Townsend’s.

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.

A robust, chocolate-backed forest skulker with clean-cut pale underparts washed gray, and a distinctive white throat and outer tail tips. Singles and pairs are shy and inconspicuous residents in the dense under-story of mid-altitude forest, between 700–1900m. May follow army-ant swarms, where it loses its fear of humans. Calls a loud downslurred quavering “tiiyuuu” and harsh chitter in alarm. Similar White-chested Alethe differs from Cholo by having gray (not brown) face and rufous tail lacking white.
