Black Kite
The Black Kite is not generally black at all but dark brown, with a light grey head characteristic of kites; it lacks the rufous-brown plumage of its larger cousin, the Red Kite. Black Kites are found over much of Europe (not UK except rare migrants or feral) and Asia. They generally eat insects and carrion/refuse with some small live prey.
