Brahminy Kite - Haliastur indus, Udawalawe National Park, Sri Lanka.

This bird is very often seen circling the clear sky in pairs wheeling in the high thermals. They make a high piercing cry of 'whee whee whee' heard all over the countryside. They swoop down on birds' nests to grab the youg chicks. Crows usually attack them in groups and drive them away protecting their young.
