Henderson petrel

During Captain Cook's voyages in the eighteenth century, Daniel Solander wrote in his manuscript of the procuring of a petrel which he named Procellaria atrata. It was not until 1912, when Gregory Mathews published Solander's account, and created this name . However, Mathews did not actually designate a new type, as what Solander had described was considered to be merely hypothetical.

The Henderson petrel is classified as Endangered (EN), considered to be facing a very high risk of extinction in the wild.

The Henderson Petrel (Pterodroma atrata) is a species of seabird in the Procellariidae family. It is found in the Pitcairn Islands, primarily Henderson. It is closely related to P. arminjoniana and P. heraldica. Its natural habitats are subtropical or tropical moist lowland forests and open seas. During Captain Cook's voyages in the eighteenth century, Daniel Solander wrote in his manuscript of the procuring of a petrel which he named Procellaria atrata. More

The completely dark Henderson Petrel (Pterodroma atrata) has been previously reported by Jaramillo et al. to the island. Kermadec Petrel has distinctive primary white shafts in the upperwing at all the phases, even in very dark individuals. This feature is normally quite distinctive in the field. It is a stocky petrel with broad wings and broad wedge-shaped tail. More

"Of most concern is the Henderson petrel, known to nest only on the island, which we believe is facing extinction. Because they are such long-lived birds, they are not likely to disappear entirely in the next few years, but they are gradually heading down the slope. Removing the rats would restore normal breeding success at a stroke, and allow the seabirds to gradually recover to their former glory, averting extinction for Henderson petrel." Planning is now underway for an expedition to the remote island. More

other authors, Henderson Petrel has whitish patagium, a fade silvery look at the base of primaries and lighter areas around the chin. The bird on the picture resembles the jizz of Kermadec Petrel; colour features such as the contrasting lighter face area and whitish panel on the underwing are also present. In dorsal view it is possible to see that the shafts are dark coloured, hence we suppose this could be a potential Providence Petrel (Pterodroma solandri). More

identification of Henderson Petrel (see above photo), which should perhaps be considered a tentative sighting on our trip. Seeing these birds raises some important questions: Are all dark "Herald Petrels" in the Pacific Ocean in fact Henderson Petrels? Conversely, is there a dark-morph Pacific Herald Petrel with which Henderson Petrel can be confused? If so, how does one separate the two species at sea!!?? - Fig. 10. Author/photographer at work.
