All five frigatebird species have a tropical distribution. The Ascension Frigatebird is endemic to Ascension Island and breeds at only one location - Boatswainbird Island. The population is thought to number about 10,000 birds, although current census work by the Royal Society for the Protection of Birds aims to produce an up to date assessment of population size. Ascension Frigatebirds can be seen around all coasts of the island. They are easiest to see in the North-east Bay area, where birds can be seen flying along the coast to and from Boatswainbird Island. Better views can be obtained from Letterbox where frigatebirds can be seen roosting on the cliff tops, or alternatively from a boat trip around Boatswainbird Island.
