Behaviour

This bird is a transequatorial migrant, venturing to subtropical waters near Japan before returning to its breeding grounds. It has also been sighted well off the western coast of the United States.

Breeding

The breeding habits of Stejneger's petrel involve nesting in burrows. It shows a preference for slopes and ridges surrounded by dense fern forests where it can safely rear its young.

Conservation status
