Black-bellied Storm Petrel Field ID Keys

Shape & Size

Fairly large storm petrel with broad wings, square tail and toes often projected beyond tail.

Colour Pattern

Black and white seabird with upperside grayish-black with a white rump. The underside is mainly white with a dark longitudinal central band that is not so easy to see at sea.

Behavior

Pelagic bird normally seen offshore. It is often seen in association with Wilson’s Storm Petrel. (Howell, 2012)
The flight description of the first record of this species to the Western Palearctic, is that “its flying behaviour resembled the bouncing movement of a Wilson’s Storm-petrel, but with higher and longer ‘jumps’.” (Correia-Fagundes & Romano, 2011)

Habitat

Fregetta tropica breeds from October to April in the sub-antarctic islands and moves northward from May to September to subtropical waters of the Atlantic Ocean

Distinction from similar species

It is easily mistaken with White-bellied storm petrel Fregetta grallariabeing the key features to distinguish them the chin - white on Fregetta tropica and dark on Fregetta grallaria - and the lack of the central longitudinal dark band on the White-bellied storm petrel.
