The Two Peoples Bay and Mount Manypeaks Important Bird Area is a 261 km2 tract of coastal and subcoastal land east of the city of Albany in south-west Western Australia. It is an important site for the conservation of several rare and threatened birds. The site has been identified as an IBA by BirdLife International because it contains almost the entire population of Noisy Scrub-birds, a large proportion of Western Bristlebirds and most of the western subspecies of Western Whipbirds.
It also supports over 1% of the World populations of Flesh-footed Shearwaters and, probably, of Great-winged Petrels, as well as significant numbers of Short-billed Black Cockatoos, Australasian Bitterns, Western Rosellas, Red-capped and Rock Parrots, Red-winged Fairywrens, Western Spinebills, Western Thornbills, White-breasted Robins and Red-eared Firetails. Hooded Plovers are regularly seen. Mammals found in the IBA include Gilbert's Potoroos, Quokkas, Western Ringtail Possums, Honey Possums, Western Brush Wallabies and Quendas.
