Trindade petrel

The petrel has 2 color morphs, a dark phase and a light phase, with intergrades between the two also occurring. There are also 2 separate populations, one occurring in the south Pacific, sometimes seen in Hawaii; the other occurring in the south Atlantic, nesting off Brazil, with rare sightings in the Gulf Stream off the southeastern United States. The little-known Pacific subspecies Pterodroma heraldica may be a distinct species . It uses oceanic islands, atolls, nesting on cliff ledges, ridges or rocky slopes. On some islands, nesting birds are threatened by feral cats and rats.

The Trindade petrel is classified as Vulnerable (VU), considered to be facing a high risk of extinction in the wild.

The Trindade Petrel, Pterodroma arminjoniana, is a species of seabird and a member of the gadfly petrels. The bird is 35-39 cm in size, with a 88-102 cm wingspan. The petrel has 2 color morphs, a dark phase and a light phase, with intergrades between the two also occurring. More

Trindade Petrel nests in Brazilian waters and ranges regularly into Gulf Stream waters off east coast of the United States. In addition, there are at least two records from the Azores (18th July 1997 and 17th May 2006). Here are the pertinent comments from his email: "On Sept. 30 we were in Zodiacs 0.5 miles south of the southern tip of Brava Island in the Cape Verde group. More

underwing, but only separated from the Trindade petrel by absence of pale primary shafts in the upperwing and distinct call. Pale morph has less white on face and more on underwing than P. neglecta. More

Trindade Petrel is a rare but regular visitor to the waters off Hatteras. Trindade Petrel is one of six large subtropical Pterodroma petrels posing identification challenges. Trindade and Herald Petrels are very similar in appearance and both are polymorphic with dark-, white-, and intermediate-belly colors. Trindade Petrel breeds on Round Island in the Indian Ocean and on Trindade Island and Martin Vaz Rocks in the South Atlantic. They have been recorded from May-late September off North Carolina. More

the Trindade petrel on Trindade Island (near Brazil). Interestingly, they had found little difference between these two island bird populations whether it was based on genetic markers, morphology or calls and yet they hosted different lice species. We knew this thanks to the expert identification skills of Ricardo Palma based at the Museum of New Zealand Te Papa Tongarewa and whom I had collaborated with before on Pectinopygus lice on pelicans.

but that hosted by Trindade petrels elsewhere has not been reported from Atlantic waters, possibly indicating earliest colonisation by Kermadec petrels. The morphometrics of Trindade petrels in the Atlantic Ocean cannot be established accurately until the generally larger Kermadec petrels are excluded from data sets. - This mail sent through IMP: http://horde.

light morph Trindade Petrel, which only breeds on islands off the coast of Brazil. This is not the individual we saw, but one from a trip this May. Photo courtesy of Steve Howell. Use only with permission. June 28 to July 5 Half Day Fishing Summary Scrappy inshore fishing continues with plenty of bottom fish, but few keepers. This might improve as some of the triggers move inshore w/ the warmer water. More

Previously mistaken for Trindade petrels (Pterodroma arminjoniana) at Ilha da Trindade, they were identified by the whitish shafts and largely white inner webs of their primaries and, at the colony, by their distinctive call. Records of five non-breeding Kermadec petrels in the North Atlantic Ocean include the first Atlantic specimen from western United Kingdom in 1908. More
