A SURVEY OF THE BREEDING SEABIRDS AND MIGRATORY SHOREBIRDS OF THE HOUTMAN ABROLHOS, WESTERN AUSTRALIA.

The article presents the results of a brief survey regarding the breeding seabirds and migratory waders at the Houtman Abrolhos, Western Australia. It states that the survey compares population sizes of the major seabird colonies to the studies conducted in the 1990s where the long-term changes in the location of breeding colonies are identified. The survey also involves the study of 192 islands, islets and rock over 21 days in December 2006 in which the seabird nesting habitat was mapped. The survey recorded 14 species of seabirds, three resident shorebirds, and two raptors which were breeding. Results show a decrease in the population sized of some species such as Wedge-tailed Shearwater and increase in other species such as Puffinus assimilis.
