The Slender-billed Prion is a medium-sized prion with a noticeably slender bill compared to other prions. It inhabits the cool temperate waters of the Southern Ocean.
Where to spot
Circumpolar in the cool temperate Southern Ocean, breeding on the Falkland Islands, Kerguelen Islands, and islands off Chile. Disperses widely, sometimes reaching South Africa.
How to spot
Identify by its blue-grey upperparts, white underparts, and a distinct black 'W' or 'M' pattern across its upperwing. The key feature is its noticeably slender bill. Its flight is erratic and undulating. Best observed during pelagic trips in the Southern Ocean.
When to spot
Breeding occurs during the austral summer (September-April). Can be observed at sea year-round throughout its oceanic distribution, often in large flocks.

Its specialized slender bill allows it to feed on a wider variety of prey than other prions, including small fish and squid, in addition to krill.
