Tourville and Murat Bays Important Bird Area is an important bird area in South Australia with a combined area of 117 square kilometres (45 square miles), located west to the town of Ceduna on the north-west corner of the Eyre Peninsula in the Great Australian Bight.
Tourville Bay has a relatively narrow neck and contains extensive intertidal flats and saltmarsh.
[1] The bays have been identified as an IBA by BirdLife International because, together, they support over 1% of the world populations of both pied and sooty oystercatchers.
[2] Other birds for which the site is important include common greenshanks, red knots, sharp-tailed sandpipers, banded lapwings, red-capped plovers and fairy terns.
There are also records of hooded plovers, pied and great cormorants, and white-faced herons.
