Corsican Finch

Large, fairly common shearwater of the western Pacific. White underparts, brown upperparts, and a mottled brownish-white head distinctive. Forages in both shelf and pelagic waters, often forming large flocks that prey on small fish pursued by larger predatory fish. Languid, gull-like flight except in high winds, when flight more wheeling, in large arcs. Occasionally seen from shorelines, especially during storms.

A large cuckoo with an impressive tail and a rich maroon throat and breast. Found in low-to-moderate elevation deciduous woodlands. The similarly shaped Hispaniolan Lizard-Cuckoo is smaller, has a longer and straighter bill, and is gray on the chest. The most common vocalization is a “ooo-whaaa,” given in a series. The impressive “dawn song” is a series of harsh, ratcheting utterances that accelerate in frequency and grow ever briefer in duration: the first few notes are “ooo-whaaaa,” becoming “whaa” as the song progresses.

Small, terrestrial bird that is endemic to Galápagos. Adult is dark gray with a brown back, red eyes, and fine white speckles on the rear half of the body. Juvenile is mostly gray and lacks white speckles. Now found only at higher elevations in the interior of larger islands, but formerly also occurred in coastal mangroves. Furtive and hard to see as it skulks in dense vegetation, such as tall grass and tangled forest understory. Varied vocalizations include clucks, churrs, squeaks, and extended rattles.
