Pair of Red-billed Tropic Birds Flying This striking pair of Red-billed Tropic Birds is soaring back to the cliffs where their colony nests. Tropic birds are plunge-divers that feed on squid and fish far out at sea. After a dive, they bob back up and sit briefly on the surface with their two tail feathers held upright. Tropic bird courtship is an intricate aerial display. They make their nests on ledges and in holes and crevices in the cliffs, and lay a single egg on the ground. Both parents share incubation and feeding of the chick. The juvenile tropicbird looks like its parents except that its bill is yellow. South Plaza Island.
