Prinia Discards Parasitic Cuckoo Finch Egg

The film clip shows a nest of the most frequent host of the cuckoo finch, the tawny-flanked prinia, which has an extravagantly diverse range of eggs. The prinia parent has recognised that an egg in its nest is that of a cuckoo finch, and proceeds to eject it by spearing it on the end of its beak and carrying it away.
