分布与栖息地
Its natural habitats at tropical moist lowland primary forest and secondary forest up to 1,300 meters above sea level. While they can tolerate secondary forest, they have the highest population densities and health in primary (old-growth) forest.<p>The IUCN Red List has assessed this bird as vulnerable with the population being estimated at 6,000 to 15,000 mature individuals. Its main threat is habitat destruction through both legal and Illegal logging, conversion into farmlands through Slash-and-burn, charcoal burning, and mining. Its preference for low altitudes suggests that it must have suffered population losses with the loss of lowland forest in the Philippines. Habitat loss on both Negros and Panay has been extensive. By 2007, Negros and Panay had a 3% and 6% remaining forest cover with most of this being higher elevation forest where this bird does not thrive in with these figures are still declining.<p>It occurs in a few protected areas on Northern Negros Natural Park, Mount Kanlaon National Park and Northwest Panay Peninsula Natural Park. However, as with most areas in the Philippines, protection from hunting and illegal logging is lax. <p>Conservation actions proposed are surveys particularly on Panay, to identify further key populations. Formally protect the Central Panay Mountain Range and other key sites. Promote more effective protection measures for the Northern Negros Natural Park. Encourage careful reforestation activities around remaining forests with emphasis on native trees.

Nicaraguan Grackle
Quiscalus nicaraguensis
Long-tailed blackbird, very similar to Great-tailed Grackle but smaller. Male is darker black with less obvious glossiness (but still some, usually greenish); female is very similar to female Great-tailed but paler below. Extremely limited range in the vicinity of Lake Nicaragua and Lake Managua, where small flocks can be found in open grasslands and wetlands.
Southern Scrub-Flycatcher
Sublegatus modestus
Small, dull flycatcher. Medium brown with a light yellow belly, and two whitish wingbars. Breeds in dry scrub and open woodlands across much of southern South America; also a common austral migrant into Amazonia, where it is found in secondary and successional growth. Compared to the similar Amazonian Scrub-Flycatcher, Southern has a brighter yellow belly, and crisper, brighter white wingbars.
Wattled Ploughbill
Eulacestoma nigropectus
A fairly small, plump bird with a unique bill shape of montane forest. Male is yellow-green with black wing, chest, and two large, pink, fleshy wattles beside the bill. The female is olive-green with paler underparts. Forages low and especially likes climbing bamboo. Uses its strong bill to strip wood and dig into branches. Male plumage is unique, but even with the female’s non-descript plumage, the bill shape should be a give-away. Voice, a single, long, high-pitch note.
