Description
edit
Ebird describes this as "A medium-sized bird of lowland and foothill forest. Slender, with a medium-length bill and tail. The male is entirely black with some blue gloss on the back and crown. Female is slaty-gray with a blackish face and tail. Female is similar to Black-bibbed Cuckooshrike, but larger and more uniformly dark gray in color. The black male differs from other black birds like Philippine Fairy-Bluebird and Asian Glossy-Starling by its dark rather than red eye. Song is a forceful, descending whistle, “tiiuuuu!” [2] It is presumed to feed on insects but diet is unknown.
Habitat and conservation status
editIts natural habitat is tropical moist lowland forest up to 1,000 m where it forages in the canopy and upperstorey in mixed-sepcies flocks. [3]
The IUCN Redlist has classified this species as least-concern but is declining habitat loss due to deforestation for lumber, mining and farmlands. There are no known targeted conservation actions for this bird, but it will indirectly benefit from the conservation of other North Luzon species like the Critically Endangered Isabela oriole.
It occurs in protected areas like Northern Sierra Madre Natural Park, Bataan National Park, Aurora Memorial National Park, Quezon Protected Landscape but actual protection from deforestation and hunting are lax.
