Bulwer’s Petrel

The Bulwer’s Petrel (Bulweria bulwerii), is a small seabird in the family Procellariidae. It is one of two species in the genus Bulweria. This bird is named after the Scottish naturalist James Bulwer. This seabird breeds in the north Atlantic in colonies on islands in the Cape Verde Islands, Azores, Canary Islands and Madeira groups. Bulwer’s Petrel also breeds on islands across the north Pacific from east of China to Hawaii.

After breeding, birds disperse to spend the rest of the year at sea, mainly in tropical waters. This species has been recorded in Europe as a rare vagrant to Ireland, Great Britain, Portugal and the Netherlands. It has also appeared as a vagrant in North America, with rare sightings far off the coast of both California and North Carolina.

This very long-winged petrel is 9.8 to 11.5 inches in length with a 30 to 35 inch wingspan. It has mainly brown plumage and a long pointed tail. It has a buoyant twisting flight as it picks planktonic food items from the ocean surface.
