svartkronebatis Batis erlangeri

A typical black, white, and dark-gray batis. Note the chest band, which is black in males and chestnut in females. Found in woodland and moist savanna, often in pairs. Very similar to Gray-headed Batis, and best distinguished by voice, but also usually shows a darker gray crown. Also similar to Senegal and Pale Batises, but has a narrower white eyebrow stripe than the former and is darker overall than the latter. The distinctive song is a series of hollow whistles on the same pitch.
