Papasula abbotti (Abbott's Booby)
Synonyms: Sula abbotti
Abbott’s Booby (Papasula abbotti) is an endangered seabird of the sulid family, which includes gannets and boobies. It is the largest bird of the family, and is placed within its own monotypic genus. It was first identified from a specimen collected by William Louis Abbott, who discovered it on Assumption Island in 1892. Abbott's Booby breeds only in a few spots on the Australian territory of Christmas Island in the eastern Indian Ocean, although it formerly had a much wider range.
The Abbott’s Booby has a unique breeding biology, behaviour and bone structure that sets it apart from the six other booby species. Once widespread throughout the Indian and Pacific Oceans, this endangered species is now restricted to a breeding colony on Christmas Island, an Australian territory located in the eastern Indian Ocean. Unfortunately, this unique booby is threatened by a large number of factors, not least of which is the yellow crazy ant. This invasive ant species causes havoc with the island’s ecology, killing red crabs that play a key role in soil fertilization and turnover. Much of the booby’s forest habitat has been cleared for the mining of phosphate. The species is also threatened by wind turbulence, marine pollution, overfishing, harvesting and invasive exotic plants.
