Oregon Islands National Wildlife Refuge, National wildlife refuge on Oregon coast, US.

Oregon Islands National Wildlife Refuge is a nature reserve that runs along the Pacific coast of Oregon from Tillamook Head to the California border. It covers around 1,900 rocks, reefs, and islands scattered along the shoreline.

The refuge was established in 1935 by the federal government to protect marine mammals and seabirds from hunting and human disturbance. It was one of the first steps taken to protect the natural habitats along the Pacific coast.

Thirteen seabird species nest on the refuge's rocks, among them tufted puffins, common murres, rhinoceros and Cassin's auklets, pigeon guillemots and Leach's storm-petrels. More than 1.2 million birds nest in these colonies, a larger number than on the California and Washington coasts combined. Coquille Point at Bandon is one of the mainland spots from which the colonies can be watched.

The islands themselves cannot be visited on foot, so wildlife watching from the shore or on a guided boat tour is the main option. Visitors who arrive by small plane should know that a minimum flight altitude applies over the protected areas.

The southern part of the refuge holds the largest Steller sea lion breeding and birthing site outside of Alaska, which many visitors do not realize. These animals return to the same spots each year and can be watched from the shore.
