Buller's Shearwater is a medium-sized shearwater with a striking plumage pattern, breeding in New Zealand and migrating to the North Pacific. It is known for its agile flight.
Where to spot
Breeds on islands off New Zealand (e.g., Poor Knights Islands). Migrates to the North Pacific, foraging extensively from California to Alaska and across the central Pacific.
How to spot
Easily identified by its pale grey upperparts, white underparts, and the distinctive black 'M' or 'W' pattern across its upperwing and a black cap. Its flight is graceful, with long glides and banking turns. Best observed on pelagic trips off New Zealand (winter) or western North America (summer).
When to spot
Breeding occurs during the austral summer (September-April). Most commonly observed in the North Pacific during the northern summer (May-October).
