Collared Petrel

The Collared Petrel, known scientifically as <em>Pterodroma brevipes</em>, is a seabird belonging to the family Procellariidae, the petrels and shearwaters. <em>Pterodroma brevipes</em> is a gadfly petrel characterised by its typically dark upperparts contrasting with paler underparts, and by a distinctive collar or partial collar pattern on the breast and neck. The species is highly pelagic, spending much of its life at sea and returning to land only to breed on remote oceanic islands. It is reported to occur in Norway according to available range data. Like other gadfly petrels, <em>Pterodroma brevipes</em> is a dynamic flier, capable of soaring at speed in strong winds. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Petrel is currently assessed as Vulnerable on the IUCN Red List, reflecting population concerns likely associated with threats at breeding colonies including introduced predators and habitat degradation.
