Description

The Trindade petrel (Pterodroma arminjoniana) 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. On some islands, nesting birds are threatened by feral cats and rats. Due to ongoing habitat loss and small breeding range, this species is evaluated as vulnerable on the IUCN Red List of Threatened Species. The specific name is after Vittorio Arminjon, captain of the ship during on the voyage in which the specimen was collected.

Feeding Habits
Trindade Petrel primarily feeds on cephalopods, captured by surface seizing or plunge diving. Trindade Petrel exhibits nocturnal foraging behavior, utilizing moonlight. Unique adaptations include specialized olfactory senses for detecting prey scent trails on the ocean surface.
Habitat
Trindade Petrel predominantly inhabits the open ocean, displaying a highly pelagic lifestyle. This species chooses remote oceanic islands for breeding, favoring locations with cliff ledges, ridges, or rocky slopes. Nesting territories can extend up to elevations of 1000 meters, often amidst dense shrubbery and grass. Trindade Petrel spends considerable time on the high seas and is rarely seen near land except during breeding periods.
