CONSERVATION STATUS

Least Concern

The Audubon's Shearwater breeds on islands in the Caribbean Sea and ranges in waters of that sea, the Gulf of Mexico, and the Atlantic Ocean off the coast of the eastern United States. Formerly, this species was "lumped" with similar small shearwaters in the eastern Atlantic, and the Indian and Pacific oceans. However, genetic studies have shown that most of these disparate populations pertain to distinct species. The Audubon's Shearwater has an estimated population of 3,000-5,000 pairs, and a conservation rating of Least Concern.

SUMMARY

Overview

Audubon's Shearwater: Small, stocky seabird with dark brown upperparts and white underparts. Underwing coverts are white. Tail is dark brown with short, gray undertail coverts. Bill is dark and legs and feet are pink. Fish and squid make up most of its diet. Alternates rapid wing beats with glides.

 

Range and Habitat

Audubon's Shearwater: Ranges across tropical parts of the Indian Ocean, north to the Arabian Sea, throughout the north-eastern and central Pacific Ocean, and the western Atlantic Ocean. Wanders northward along the Gulf Stream from the Caribbean and Bermuda as far as the Carolinas and New England. Breeds mainly on oceanic islands, coral atolls and rocky offshore islets.

INTERESTING FACTS

  • The Audubon’s Shearwater feeds in a variety of methods, both diving below the surface to chase prey, pursuit plunging, and surface feeding. Unlike other birds of its genus, it is not a ship follower.
  • Their twittering calls and mewing are often only heard at night in the breeding colonies.
  • They breed throughout the year and a successful pair can produce a chick about every 9-10 months.
  • A group of shearwaters are collectively known as an "improbability" of shearwaters.
