The Low Rocks and Sterna Island Important Bird Area comprises two islets lying about 14 km apart and with a collective area of 14 ha, in the Montesquieu group of islands, in the mouth of Admiralty Gulf in the Kimberley region of Western Australia.
Low Rocks is a 4 ha islet with a covering of grass and low scrub. Sterna's vegetation is dominated by pindan wattle and Triodia microstachya, but there are also bare sandstone ledges used by nesting seabirds. Low Rocks is a nature reserve, while Sterna is unallocated crown land. Average annual rainfall in the area is about 900 mm.[1]
The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world population of roseate terns, with up to 4000 breeding pairs using the site.[2] Other seabirds recorded as breeding in the IBA include crested and lesser crested terns, and pied cormorants.[1]
