Caspian Tit

Heavily-marked reddish-brown falcon, found in open habitats across much of the Indonesian Archipelago. Dense spotting on back and wings contrasts sharply with gray tail. Sexes generally similar, but female averages more densely patterned, with fine barring on the tail. The only resident kestrel throughout much of range, but potential for overlap with Australian and Eurasian Kestrels exists; note densely-patterned underparts, overall richer and darker coloration, and dark brown crown. Hovers and hunts from an exposed perch. Gives shrill yaps and squeaks.

Large, dark, powerfully-built owl. Has orange eyes and rufous tones to the plumage, on both the back and the underparts. Found in rugged and rocky terrain, mainly in the mountains, though down to sea level in southern Africa. Uncommon to rare across its range. Call is 2–3 deep hoots. Similar to Spotted Eagle-Owl, but larger, with bright-orange eyes, more rufous in the plumage, and coarser markings below.

Flocks of these large sea ducks enliven northern coastlines. Males are white and black with a soft suffusion of green on the nape. Immature males are variable and messy-looking with patches of black and white. Females vary from rich rufous-brown to cold grayish, always with extensive black barring covering body and wings. Slight variation in bill shape and color across subspecies, especially obvious on males; Pacific birds have brightest orange bills, most others have greenish bills. Dives to feed on mollusks and other crustaceans. In late summer, look for flocks of females with dozens of ducklings; broods often join together. Compare females with other eider species, and note details of bill and head shape.
