Onychoprion anaethetus

Bridled Tern - breeds in colonies on rocky islands in a scrape on the ground and only lays one egg. This is a plunge diving tern feeding on small fish. Also often picks from the surface. The male offers fish to the female as a courtship ritual. I met up with a huge colony of these handsome birds on Lady Elliot Island, Queensland, Australia where these images were taken.
