分布与栖息地
The giant scops owl is known only from the islands of Dinagat, Siargao and Mindanao in the Philippines. Although it has not yet been proven, it has been theorized that giant scops owls also exist on Marinduque, situated off the island of Luzon. Its habitat is primary and secondary forests, mostly at an altitude of under 670 m (2,200 ft) although it has been seen up to 1,300 m (4,300 ft). It sometimes frequents partially logged forests of Dipterocarpaceae species.

Cuban Palm-Crow
Corvus minutus
Endemic to Cuba. A large, all-black, gregarious species of open woodlands, scrub, and palm savannahs; often found in flocks of up to fifty birds. Note this species’ relatively short, stout bill with extensive feathering on top. Compare with Cuban Crow, which has longer bill with less extensive feathering on top. Vocalizations are predominantly a flat, nasal “raaah,” which is rather different from any of the various calls of Cuban Crow.
Chestnut-crested Antbird
Rhegmatorhina cristata
Striking, medium-sized antbird, brown above and rich chestnut below, with a black face and broad white bare eye-ring. Females have thin black bars above. Inhabits the understory of humid forest, where it is always found foraging at army-ant swarms. The song is a series of ascending whistles that finishes with harsh descending notes.
Ruddy Quail-Dove
Geotrygon montana
Shy and infrequently seen, rather chunky dove of tropical forests and plantations in the lowlands and foothills. Walks stealthily on the forest floor singly or in pairs. Most often seen as it flushes explosively from underfoot or flies low across a quiet road or trail. Bright ruddy-colored male is distinctive. Female is brown overall with a trace of the male’s facial pattern and has a pale vertical bar on the sides of the breast. Females lack the white tail corners as seen on White-tipped Doves and related species.
