Oriental Skylark

One of the most common and conspicuous of the Galápagos finches. Bill is at least as long as the bill is deep, with the upper edge slightly rounded. Lower edge of bill is mostly straight. Bill is moderately stout-looking, but bill size varies between individuals, and not all birds can be accurately identified. Bill is black on breeding male and dull orange on female and nonbreeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are streaked with gray. Large Ground-Finch’s bill has bulbous appearance and usually forms a ridge where it meets the crown. Small Ground-Finch’s bill is smaller and more pointed. Found in a wide variety of habitats on most islands, but absent from Española and Genovesa.

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.

A large and chunky babbler found very locally in limestone hills covered with dry forest. Rufous-brown overall with a black-streaked throat and a white-streaked back. Forages close to the ground, often in and around rocky cracks and crevices. Song is a loud, ringing, rather hoarse-sounding sequence of whistled notes including some repeated phrases, sometimes given as a duet by a pair. Also gives harsh “grrr” notes. Similar to Streaked Wren-Babbler, but larger and longer-tailed, with bolder striping on the throat and no white spots on the shoulder.
