Spot-winged Wood-Quail
Odontophorus capueira
Plump, terrestrial partridge-like bird with a short stout bill, red eye, chestnut crown, orange eyebrow, gray throat and belly, and mottled brown back. Usually encountered in small groups scampering across the ground in lowland Atlantic Forest. Song is a loud, fast, and repetitive “kloh-kloh-klohkloh.”
识别特征
Male and female spot-winged wood quails are similar in appearance but the female is slightly smaller. The bird has a reddish-brown crown with a loose crest, speckled with buff. The supercilium (stripe above the eye) and the chest-band are reddish-cinnamon. The upper parts are greyish-brown, with dark vermiculations and speckling, with the individual feathers on neck, mantle, back and scapulars having white streaks beside the shaft. The sides of the head, throat and underparts are slatey-grey. The legs are dark grey, the bill is blackish, the iris brown and the bare area around the eyes red. The length range is about 26 to 30 cm (10 to 12 in). Juveniles are similar in colouring but have reddish bills, more speckled upper parts and grey underparts flushed with rust and speckled with white.

行为
Spot-winged wood quails tend to move around on the ground by day in small groups of typically six to eight, but sometimes up to fifteen. When disturbed they move off into the undergrowth and seldom take to the wing, especially when the group includes chicks. The birds sometimes freeze and crouch. The diet includes fallen nuts of Araucaria and other trees, the berries of pokeweed and other plants and probably invertebrates. At night these birds roost well off the ground in trees. They are monogamous and breeding takes place between August and November. The nest is built on the ground with a side entrance and a roof of dead leaves. About four white eggs are laid which soon become discoloured. The female incubates the clutch, which hatch after about eighteen days, and she also rears the chicks without help.

Compact Weaver
Pachyphantes superciliosus
Has a typical weaver color scheme but an unusual shape: a chunky body, heavy bill, and short tail. Breeding males and females have a black mask, and the crown is yellow in males and black in females. Non-breeding birds are more distinctive than typical non-breeding weavers: buff below, with a dark crown and eye-stripe. Found in wet and grassy microhabitats within savanna, forest, scrub, and cultivation. Usually in small flocks. Along with typical weaver “chit” notes and sizzling, “radio static” song, also often gives a “cheep” call. Superficially similar to other weavers, but separated by distinctive shape.
White-tailed Hawk
Geranoaetus albicaudatus
Strikingly patterned raptor, usually found in open grassy areas or agricultural fields with scattered bushes. Wings are long and pointed but broad at the base which makes the tail look relatively short. Adults are clean white below with gray upperparts and rufous patch on shoulder. Tail is white with black band near the tip. Young birds are darker with dark markings on the belly; especially note dark gray wings, pale grayish-brown tail, and wing shape. Hovers more frequently than other large raptors. Widespread in Central and South America; limited range in U.S.
Philippine Serpent-Eagle
Spilornis holospilus
A fairly large, common raptor of forest and more open wooded areas from the lowlands to the lower mountains. Dark brown with white speckles on the crown and upperparts, rufous-brown below with large white spots. Note the gray cheek and yellow eye. Differs from other raptors in its range by its bare yellow skin between the bill and eye, and in flight by its dark terminal band to the wings and tail. Often gives a whistled “weeeeeuuuu weu weu” in flight, or sometimes just a single note.
