Wedge-tailed shearwater


Wedge-tailed Shearwater in flight (Philip Griffin)

Shearwaters are fast flying seabirds that flies close above the water surface far out at sea, feeding on small fish and invertebrates.

They pick their prey from the water surface or dive to catch it, using their wings and feet to propel themselves underwater. At night, they return to nesting colonies on land, making weird wailing noises as they fly in to land and throughout the night. They nest underground in burrows and under rocks, and suitable predator free islands are densely covered in shearwater burrows, Their young fat chicks were traditionally collected as food. Now, most breeding colonies are protected by law.

Wedge –tailed Shearwaters on Cousin can dive to a depth of 60 metres to catch fish , but usually stay within 20m of the surface.
