Olive-headed Weaver

This Galápagos finch is confined to the island of Genovesa. It has a fairly large bill that appears slightly elongated. The only other finch on Genovesa with a similarly-sized bill is Large Ground-Finch. Compared to that species, Genovesa Cactus-Finch has a smaller, less rounded bill that is noticeably longer than it is deep. Bill is pure black on breeding male, and marked with yellow or orange on female and non-breeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are blotched with gray. Common in arid areas near the coast, and often seen feeding on prickly pear flowers.

Striking large shearwater with distinctive dark "M" pattern on upperwings. Also note crisp dark cap and clean white underwings and belly. Looks silvery-gray above when fresh, but worn birds can be more brownish. Graceful flight style. Usually easily separated from other shearwaters by wing pattern. Breeds on islands off New Zealand; ranges across the Pacific during nonbreeding season; uncommon off the west coast of the U.S. in fall. Rarely seen from land, prefers to stay offshore. Found singly or in flocks with other shearwaters.

A medium-sized brown-and-white shearwater with darker upperparts extending to the head. A dark brown mottled collar extends down from the neck and fades into the white breast and underparts. The underwings have an off-white central patch that merges into the dark borders of the wing with distinctly dusky “armpits.” Breeds solely on the mainland of New Zealand, where nesting is restricted to steep tussock slopes in the alpine zone of the Seaward Kaikoura mountains. Slightly larger and darker than the Fluttering Shearwater, with less white showing on the chin and throat.
