About the Trindade Petrel

The Trindade petrel (Pterodroma arminjoniana), also known as the Round island petrel, is a species of seabird and a member of the gadfly petrels. The bird is 35–39 cm (14–15 in) in size, with an 88–102 cm (35–40 in) wingspan. The petrel has various color morphs: dark and light, as well as intermediates between the two. Previously, two separate populations were considered conspecific, one occurring in the south Pacific, sometimes seen in Hawaii; the other occurring in the south Atlantic, nesting off Brazil, with regular sightings in the Gulf Stream off the southeastern United States. The little-known Pacific birds were then split and determined distinct as the Herald petrel, Pterodroma heraldica. It uses oceanic islands and atolls, nesting on cliff ledges, ridges or rocky slopes.
