Galapagos Shearwater
Puffinus subalaris
Very small black-and-white shearwater of warm tropical waters. Can be seen from shore off the coast of Oaxaca. Often in flocks, sometimes of thousands, resting on the water and in feeding flocks with Brown Boobies, Black Terns, and other shearwaters. Flight quick and low, with hurried wingbeats and only short glides. Smaller and shorter-winged than Black-vented Shearwater and rare Townsend’s Shearwater. Black-vented has messier brown colors on the side of its head, without distinct dark cap of Galapagos. Townsend’s is blacker above with white patches (saddlebags) at sides of rump.

Northern Fiscal
Lanius humeralis
Long-tailed black-and-white shrike. There is a V-shaped white mark on the shoulders, a small white nick on the bottom of the wing, and white in the outer tail. Juveniles are brownish and heavily barred. Found in a wide variety of open habitats, including moist scrub and savanna, farmland, and grassland. Often solitary. Perches out conspicuously on fence poles, dead trees, and electric wires. The song is a highly variable mix of clear whistles and rougher notes. Also gives low, rough calls. Separated from similar shrikes by its black rather than gray back.

Cinnamon Woodpecker
Celeus loricatus
One of several species of mostly rufous woodpeckers with a crest. On Cinnamon, look for pale off-white belly with black scaling, and uniformly rufous head and back. Sexes mostly similar; male has red mustache stripe. Mainly a forest bird, found singly or in pairs, usually at middle levels or in the canopy. Listen for series of loud breathy whistles descending in pitch, similar to several other species in this genus.
