Storm-Petrels

Wilson’s Storm-Petrel, Oceanites oceanicus

Family Hydrobatidae (Storm-Petrels)

Size: 7"

Season: Spring–fall

Habitat: Coastal or offshore oceanic waters

The Wilson’s storm-petrel is a small seabird that breeds in far southern islands and Antarctica, dispersing to the Northern Hemisphere during our summer. The wings are relatively short and rounded, the tail is square or slightly rounded, and long, thin legs extend beyond the tail. The head is large with a steep forehead and a stubby, tube-nosed bill. The plumage is grayish brown overall, except for a crisp, white rump patch that extends to the sides of the lower flanks, and pale edges to the inner coverts of the upper wings. Wilson’s storm-petrels have purposeful flight with shallow wing beats, akin to a tern, dangle their feet, and skip along the water’s surface while feeding. They gather in large groups at sea and commonly follow fishing vessels and whales. The adult is illustrated.
