Brown-headed Thrush

Fairly small dark hummingbird, green overall with dark blue tail. Straight, medium-length bill. Copper rump and absence of rufous wing flash help distinguish from other similar species. Sexes similar. Usually seen feeding singly in flowers along forest edge, shrubby second growth, and gardens.

The smallest loon, with a slender neck and bill. Often holds the thin bill at an upward angle. In breeding plumage, note smooth gray head, brick-red throat, and dark back. In winter, dark cap and hind neck contrast with white face and throat. In flight, often lowers and raises head more than other loons; also note small feet. Juveniles can look quite dark with a smudgy gray neck and limited white throat. Often confused with other loons, especially Pacific and Arctic; note overall head and bill shape and less sharp contrast to the head pattern. Breeds on ponds in the Arctic tundra. Winters primarily on saltwater, but can use large lakes and reservoirs in migration. Sometimes gathers in loose flocks where food is plentiful.

Large, rather long-tailed, and relatively big-billed petrel of offshore subtropical and tropical waters in the eastern and central Pacific; not seen from mainland. Named for Juan Fernandez Islands in Chile, where the species breeds. Main identification features are relatively large size, gleaming white underparts with small black “comma” on bend of underwing, and dark cap blending into gray of hindneck. Upperparts show darker “M” pattern common to many petrels. Much larger than Masatierra Petrel and other small petrels.
