Brahminy Kite - Milvus indus
The Brahminy Kite occurs throughout southern and South East Asia, and in Australia, it is widespread along the north coast, though individual birds may wander inland along the course of large rivers. These raptors often perch inconspicuously for long periods on exposed perches before swooping down onto prey in the water or on the ground. Their prey usually comprises fish and insects, and they often steal food from other birds, such as gulls, terns, ibis and other raptors. They also often scavenge carrion on the ground.
