Brahminy Kites are more scavengers than hunters. But they also hunt for small prey (fish, crabs, shellfish, frogs, rodents, reptiles, even insects). They forage both over water and land, soaring 20-50m above the surface.
Prey on the water surface is snatched with their talons, Brahminy Kites don't dive into the water. They may even snatch swarming termites on the wing with their talons.
They may steal from other raptors including large ones like the White-bellied Fish Eagle. Their catch is eaten on the wing, to prevent theft. When several quarrel over a meal, they squeal.
