About the Wedge-tailed Shearwater

The wedge-tailed shearwater (Ardenna pacifica) (Uau Kani or Koto in Hawaiian) is a medium-large shearwater in the seabird family Procellariidae. It is one of the shearwater species that is sometimes referred to as a muttonbird, like the sooty shearwater of New Zealand and the short-tailed shearwater of Australia. It is found throughout the tropical Pacific and Indian Oceans, roughly between latitudes 35°N and 35°S. It breeds on the islands off Japan, on the Islas Revillagigedo, the Hawaiian Islands, the Seychelles, the Northern Mariana Islands, and off Eastern and Western Australia.

Its Hawaiian name "Uau Kani" reflects the sound of their bird call. Native Hawaiians had sometimes named birds after the nature of their melody. The wedge-tailed shearwater was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the petrels in the genus Procellaria and coined the binomial name Procellaria pacifica. Gmelin based his description on the "Pacific petrel" that had been described in 1785 by the English ornithologist John Latham in his book A General Synopsis of Birds... Wikipedia →
