Hawaiian Petrel

Rare hummingbird of cloud forest on the east slope of the Andes. Male is mostly green with darker throat and white tips to the inner tail feathers that combine to form a round spot. On female, note green scaling on white underparts, white mustache stripe, white tail corners, and buff tinge on vent (but not on thighs). Female very similar to female Booted Racket-tail but is more heavily scaled on throat and has white thighs. Typically found at forest edge or in clearings, feeding at any height, and occasionally visits feeders.

A small, gorgeous swallow with blue-black upperparts, rump, and face, and uniform rich rufous chin, throat and underparts. In flight the underwing coverts are rufous. The juvenile is duller than the adult. Singles or pairs are scarce in grassland and savanna, often associated with the edges of swamps, rivers and partially flooded areas. Similar Red-throated Swallow has a reddish rump and is less rufous below than the much more neatly-plumaged Black-and-Rufous Swallow; other similar swallows are larger with longer tails, red rumps and paler underwing coverts.

A beautiful, small grebe of Patagonia that is rare, local, and declining; breeds on a few interior lakes. Nonbreeding birds range to coastal waters and lowland lakes, where they are most often seen in the company of Silvery Grebes. Told from Silvery Grebe by more contrasting head pattern: black hood contrasts with white forehead and golden tiara, often striking at long range. Grebes are very rarely seen in flight, but wings of Hooded are mostly white unlike the dark wings with a white hind patch seen on Silvery Grebe.
