Bristlebill

The bristlebills are a genus of passerine birds belonging to the genus Bleda in the bulbul family Pycnonotidae. They are found in the understorey of forests in West and Central Africa. They forage for insects at or near ground-level, often near water. They will follow driver ant swarms to catch prey items fleeing from the ants and they frequently join mixed-species feeding flocks.

They are 18–23 cm long with fairly long, stout bills. The upperparts are mainly green-brown while the underparts are yellow. The birds have whistling songs.

The nest is made of leaves or sticks and built in a shrub or small tree. Two eggs are laid.
