This is a species which inhabits the South Pacific and Indian Oceans, and is said to rarely occur on the California coast. They breed during our winter on some of the small islands and during our summer are ocean wanderers. An egg in the collection of Col. John E. Thayer was taken on Gough Island, South Atlantic Ocean; Sept. 1st, 1888. The nest was a mound of mud and grass about two feet in height. The single white egg measured 3.75 x 2.25. It was collected by George Comer.
