EBird describes the bird as "A small woodpecker of lowland wooded areas on the Sulu Islands. Dark brown above with some white spots on the back, a white rump, throat, and underparts with faint streaking, and buffy sides of the chest.

No other similarly sized woodpeckers occur in its range. Voice includes a series of rapid notes in a forceful trill."[better source needed]<p>The species is named after Captain Wardlaw Ramsay from whose collection the species was described by Hargitt. Specimens were claimed to have been obtained from Borneo but the locality was not certain until new specimens were obtained from Sulu Island by Guillemard.

分布与栖息地
It inhabits forest clearings, forest edge, mangroves and cultivated areas, in addition to primary forest, although it has been speculated that it avoids dense forest. It is seen in altitudes up to 550 meters above sea level. However, its habitat preferences are poorly understood. Its tolerance of degraded habitats implies that it should be more numerous than is the case.<p>The IUCN Red List classifies this bird as a vulnerable with population estimates of 2,500 to 9,999 mature individuals. Although this species is supposedly more tolerant of habitat degradation, it is still threatened by habitat loss with wholesale clearance of forest habitats as a result of legal and illegal logging, mining, conversion into farmlands or palm oil plantations and urbanization. Due to the rapid loss of habitat in the Sulu Archipelago, many of the birds endemic to the region like the Sulu hornbill, Tawitawi brown dove, Blue-winged racket-tail, Sulu hawk-owl are all threatened with extinction.<p>There are no species specific conservation programs going on at the moment but conservation actions proposed include more species surveys to better understand habitat and population. Lobby for protection of remaining forest. Continue to expand environmental awareness programs and raise the species profile and instill pride in locals

Narrow-tailed Emerald
Chlorostilbon stenurus
Small, compact, short-billed and short-tailed hummingbird with green tail. Male all glittering green; female green above and gray below with dark cheek, white eyeline, and white-tipped tail. Occurs near humid forest borders in highlands (from 1800 m), usually in open areas, gardens, and cultivated areas. Often perched alone near small flowers at low height. Very similar to other emerald species; distinguished from male and female Short-tailed Emerald by having wings and tail the same length when perched; from male Green-tailed Emerald by irregular length tail feathers. Endemic to the Andes and Coastal Cordillera of Venezuela.
Flightless Steamer-Duck
Tachyeres pteneres
A large heavily built duck that is uncommon to fairly common along rocky seacoasts; not found on lakes, unlike Flying Steamer-Duck. Both sexes are steely blue-gray overall, brighter than Flying Steamer-Duck, with a stouter and deeper-based bill. The bill of both male and female is bright orange in the southern parts of its range, but is orange with a greenish distal patch around Chiloé Island (likely a different species). The bill of juvenile birds is duller grayish to dull yellowish; attains adult color by winter.
Spotted Owl
Strix occidentalis
Medium-sized owl typically found in mountainous regions with mixed conifers and oaks. Overall brown with bold white spots on belly and back. Black eyes, unlike most other owls; main confusion species is Barred Owl. Spotted is well-named, with much more obvious spots on chest and belly than Barred Owl, and lacks distinct vertical stripes. Also note voice: one hoot, followed by a pair of hoots, followed by a final single hoot. Two separate populations: birds along the Pacific coast and the Sierra Nevada average darker, richer brown than birds further south and inland.
