CONSERVATION STATUS

Vulnerable

The Stejneger’s Petrel is a seabird that reaches only 26 to 31 centimeters in size. This species is typically found on the water, rarely approaching areas of land. However, the Stejneger’s Petrel nests and rears its young in the Juan Fernandez Islands off of the coast of Chile. This bird is typically found in the Pacific Ocean. It also migrates in a transequatorial pattern, traveling to the subtropical waters of Japan before returning to its preferred nesting sites. Nests are actually burrows dug by the parents, and these birds prefer habitats in dense fern forests. The conservation rating of this species is Vulnerable.
