The Black-vented Shearwater is a common seabird of the eastern Pacific, easily identified by its dark upperparts and white underparts, with a distinctive dark undertail coverts. It is often seen in large flocks, especially during migrations.
Where to spot
Breeds on islands off Baja California, Mexico, and disperses north along the Pacific coast of North America (California to British Columbia) and south towards Central America during the non-breeding season.
How to spot
Look for them from coastal headlands, piers, or on pelagic boat trips. Identify by its dark upperparts, white underparts, and crucially, the dark undertail coverts. They fly with stiff-winged glides and occasional rapid wing beats, often in large, active feeding flocks.
When to spot
Best observed during late summer and autumn when large numbers migrate north along the coast, and throughout winter in its non-breeding coastal range. Less common in spring.

This shearwater frequently feeds in association with marine mammals like dolphins and whales, preying on baitfish driven to the surface by their larger companions.
