 MANX SHEARWATER. 



HABITS. 



Contributed by Charles Wendell Townsend. 



The Manx shearwater, so called because it formerly bred in great 

 numbers on the Isle of Man, is mainly a bird of the British Islands. 

 As it is the familiar shearwater of Great Britain and bears a general 

 resemblance to the greater shearAvater, it is probable that some of 

 the early records of this bird for America should be referred to the 

 latter species. Audubon (1840) says, "I have procured this species 

 to the westward of the banks of Newfoundland, or between their 

 soundings and the American coast." Baird, Brewer, and Ridgway 

 (1S84) say: 



Mr. Boardiiian informs uio that a single individual of this species has from 

 time to time been met with at sea off the coasts of Maine and Nova Scotia, but 

 he regards such an occurrence as something extremely uncommon and as purely 

 accidental. This bird is also mentioned as being only an accidental and very 

 rare visitor on the coast of Long Island. 



Putnam (1856) included it in the avifauna of Essex County, Massa- 

 chusetts, from a skull in the Essex Institute, of a bird said to have 

 been killed in Salem Harbor, August 13, 1855. The skull has since 

 disappeared and there is no other record or remembrance of it. Reid
