The Christmas Island frigatebird is a large, lightly built seabird with brownish-black plumage, long narrow wings and a deeply forked tail. It breeds only on Christmas Island in the Indian Ocean. The male has an egg-shaped white patch on the belly and a red throat pouch that he inflates to attract a mate. It takes fish, mostly flying fish, from the ocean surface in flight, and sometimes harasses other birds into giving up food. (Wikipedia, general species account).
