Pachyptila vittata
Pachyptila vittata, the Broad-billed Prion, is a distinctive and highly specialized pelagic seabird within the order Procellariiformes, family Procellariidae, which includes petrels and shearwaters. Measuring approximately 25-30 cm in length with a wingspan of 57-66 cm, it presents a classic 'prion grey' appearance: pale blue-grey upperparts, white underparts, and a subtle dark 'M' pattern across the wings visible in flight. Its most striking field mark, and the origin of its name, is the rem...
Primarily a pelagic marine species, inhabiting the open ocean of the Southern Hemisphere for most of its life, only coming ashore to breed on remote, predator-free subantarctic islands, nesting in burrows at sea-level.
The diet consists predominantly of small zooplankton, including copepods, euphausiids (krill), and amphipods, which they filter from the ocean surface using their specialized lamellated bill.
Broad-billed Prions exhibit a fascinating dual life, being strictly nocturnal at their breeding colonies to avoid predation by skuas and gulls, while foraging diurnally at sea. Foraging strategies are highly specialized; they skim the ocean surface, 'hydroplaning' with their broad bill submerged ...
The Broad-billed Prion (Pachyptila vittata) breeds exclusively on remote, predator-free subantarctic islands primarily associated with New Zealand. Key breeding locations include the Snares, Chatham, Auckland, Campbell, and Antipodes Islands. After breeding, adults and fledglings disperse widely ...
