Summary In counts in 1982 and 1984, this island supported one of the world's largest populations of Brown Booby and more than 1% of the world breeding population of Lesser Frigatebird.
Site description Bedout Island is situated 40 km north of the mouth of the De Grey River in the Pilbara of Western Australia. It is an undulating sand cay, vegetated with Spinifex longifolius, has an arid climate with an annual average rainfall of ca 300 mm and is subject to occasional tropical cyclones.
Key Biodiversity Additional breeding birds: 120-170 pairs Masked Booby, White-bellied Sea-Eagle, Silver Gull, Crested Tern and Lesser Crested Tern. Old records, possibly before Black Rats introduced, of Roseate Tern, Sooty Tern and Brown Noddy.
Non-bird biodiversity: Rattus rattus was probably introduced from pearling vessels late 19th century; eradicated 1991.
