cahow
The Cahow Petrel was named Cahow or Cowhaw by the early (17th century) colonists of Bermuda, in imitation of its cries;"Æstrelata cahow sp. nov.  The type specimen, a mounted bird, Coll. Bermuda Museum of Natural History, was taken by Mr Mowbray, Feb. 22, 1906, in a rock crevice, about 20 feet above high water, Southeast side of Castle Island.  ... The name "cahow" was used by early settlers in Bermuda for an Æstrelata abundant at Cooper's Island, a mile at the most from where the type was taken and presumably of the same species. Numerous partially fossil bones (including skulls) which, after comparison, we believe to belong to the form here described have been found by Mr Mowbray in various caves in the eastern end of the Bermudas, some about a half mile from where the bird was taken" (Nichols & Mowbray 1916) (Pterodroma).
