Karaca Tırtılyiyen Analisoma coerulescens

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!”
