Newell's Shearwater and Black-vented Shearwater can be challenging to distinguish at sea. Newell's Shearwater is noted for its strong, rapid wing beats with little gliding, while Black-vented Shearwater typically exhibits a more gliding flight style. Both species are similar in plumage, making behavior and habitat key differentiators.

Look for Newell's Shearwater's rapid wing beats and minimal gliding when in flight. Consider the habitat: Newell's is more likely over deep, open ocean, while Black-vented is often nearer to shore.

Both species have similar plumage, making them difficult to distinguish based solely on coloration.

Newell's Shearwater has a distinctive flight style with strong, rapid wing beats and little gliding, unlike the more gliding flight of the Black-vented Shearwater.

Newell's Shearwater is highly pelagic, often found over deep waters greater than 2,000 meters, primarily around the Hawaiian Islands. In contrast, Black-vented Shearwater is typically found closer to the coast.
