The Magnificent Frigatebird is a long-winged, fork-tailed bird of tropical oceans. 
This bird is an agile flier that snatches food off the surface of the ocean and steals food from other birds.
The male has a striking red throat pouch which it inflates to attract a mate.
The female is slightly larger than the male and has a white breast and belly.

This is a male. Ambergris Caye, Belize, 11 March 2009
