Wilson's Storm-Petrel

Wilson's storm-petrel is a small seabird with a circumpolar distribution, mainly in the seas of the southern hemisphere but extending northwards in the northern summer. It is 16 to 18.5 cm long, and one of the most abundant bird species in the world. The name commemorates the Scottish-American ornithologist Alexander Wilson (Wikipedia, general species account).

Two or three subspecies are recognised, and one New Zealand population may be extinct. The nominate population breeds from Cape Horn to the Kerguelen Islands. The old name Mother Carey's chicken was used for several petrels, and the idea that they foretold storms gave the group its name. The 2012 National Red List gives no status under this name.
