Boatswain Bird Island

Boatswain Bird Island, also spelt Boatswainbird Island, is a small island some 270 metres (300 yd) off the east coast of Ascension Island in the South Atlantic Ocean with an area of approximately 5.3 ha (13 acres). It is administered from Georgetown on Ascension, which is part of Saint Helena, Ascension and Tristan da Cunha, an overseas territory of the United Kingdom. Boatswain Bird Island should not be confused with the nearby, much smaller, Boatswain Bird Rock, only about 10 by 5 metres (33 by 16 ft) in size, located 570 metres (620 yd) south-east of the island and 360 metres (390 yd) north-east of the coast of Ascension. The southern coast of the island has an impressive natural arch.

Birds

There are thousands of inhabitants on this tiny island, all of which are birds, which give the island its white colour. Among the many seabirds nesting there are boobies, petrels, noddies, as well as the tropicbirds (boatswain birds) for which the island is named.

The island is the home of the majority of Ascension's birds due to rats (accidentally introduced by passing ships) and then cats (introduced to catch the rats, as well as pets) eating the birds and their eggs on Ascension. Since the mid-1990s there has been a feral cat eradication program, alongside a rat eradication program, to encourage the birds back to the main island.

Important Bird Area

The island has been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds. Birds for which the IBA is significant include Madeiran storm petrels (1,500 breeding pairs), red-billed tropicbirds (500 pairs), white-tailed tropicbirds (1,000 pairs), Ascension frigatebirds (6,000 pairs), masked boobies (1,300 pairs) and black noddies (5,000 pairs).[1]

gollark: This is bigger, but basically none of the members actually use it frequently.
gollark: By active member count, not really.
gollark: I assume your alts within it have already found out about this.
gollark: Esoserver currently operates a #suggestions channel into which, presumably, suggestions go and are discussed a bit. This seems to work okay without enforcing a particular style of discussion, although most bulk metadiscussion just goes in <#348702212110680064>. We haven't really had any large-scale debates happening, so who knows.
gollark: Which is still more annoying for the writer. So I'm not sure why you would expect people to interpret it as an amazing gift.
