Uses a wide range of lowland freshwater and brackish wetland habitats, including marshes, ponds, riverbanks, and mangroves. No similar large ducks regularly occur in its range. Usually in small flocks but may join wintering flocks of wigeons,shovelers, or other dabbling ducks.

保护状况
The Philippine duck is rated vulnerable on the IUCN Red List with the population estimated to be 3,300 - 6,700 mature individuals remaining. The species has experienced steep population decreases since the 1970s mainly due to hunting and habitat loss. The ducks have been heavily hunted since the 1960s with thousands being hunted a year through the late 1980s.<p>Habitat loss is mainly due to wetland drainage, aquaculture, mangrove destruction and fishpond creation.<p>The species occurs in multiple protected areas including Manleluag Spring Protected Landscape, Mounts Iglit-Baco National Park, Naujan Lake National Park, Bataan National Park, Northern Sierra Madre Natural Park and Olango Island, a Ramsar wetland. However, as is with most of the Philippines enforcement from hunting is lax.

Black-bellied Whistling-Duck
Dendrocygna autumnalis
Gangly duck with long neck and legs. Unmistakable adult has chestnut-and-black body with electric pink legs and bill. Look for the bold white wing stripe, especially visible in flight. Juvenile is duller brownish overall with gray bill and legs. Young birds could be confused with Fulvous Whistling-Duck, but juvenile Black-bellied has a white wing stripe and typically shows some black coming in on the sides and belly. Flocks gather in marshes, lakes, rice fields, and swamps, sometimes by the hundreds. Active day and night. Occurs throughout Middle and South America. Range is expanding northward in the U.S., but still largely restricted to southern states. Vocal and conspicuous; listen for wheezy whistles and chirps.
Tawny Frogmouth
Podargus strigoides
Australia’s most familiar nocturnal bird. Note bright yellow eye and very large ‘frog-like’ bill with whiskers above only slightly banded. A master of camouflage, its shaggy plumage blends in with rough bark when roosting. Usually gray but some subspecies appear more rusty-colored. Present in a wide variety of habitats and common in suburban areas.
Cliff Flycatcher
Hirundinea ferruginea
This unmistakable long-winged flycatcher is widespread (though rarely very numerous) throughout much of South America. As the name implies it occurs around cliffs, landslides, and even buildings. Medium size, warm rufous coloration (brightest on the wings), and habitat are distinctive. Some variation across range, with birds in the Andes having more whitish speckling on the face. Compare with Streak-throated Bush-Tyrant, which is larger and has a streaked throat. Usually seen singly or in pairs, perched conspicuously on a snag, rock face, powerline, or building.
