Prinia Discards Parasitic Cuckoo Finch Egg (VIDEO) University of Cambridge This video is under embargo. Please login to access this video. Caption 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.
