Western Banded Snake Eagle
The western banded snake eagle (Circaetus cinerascens) is a grey-brown African raptor with a short tail and a large head. Juveniles have paler and browner upper parts than adults, with white-edged feathers. The eagle's head, neck and breast are dark-streaked. The underparts are white with pale brown streaks, mainly on belly and thighs. Subadults may be all dark grey-brown without any streak on underparts. The eyes, ears, and legs are yellow. They have crested chests.
Western banded snake eagles mainly hunt snakes, but also other small vertebrates, ambushing from a perch. They drop from the perch to trunk, foliage or ground. They are solitary birds, and very secretive. Due to their sedentary lifestyle, they are often detected only by their calls.
The western banded snake eagle sometimes rises to soar, while it calls above the canon. They utter a loud, high-pitched 'kok-kok-kok-kok-kok'.
