MANX SHEARWATER. Puffinus 1 anglorum (Temminck). 



Coloured Figures. Gould, 'Birds of Great Britain,' vol. v, pi. 

 84 ; Dresser, ' Birds of Europe,' vol. viii, pi. 615, fig. 1 ; 

 Lilford, Coloured Figures,' vol. vi, pi. 60. 



The Manx Shearwater is common and widely distributed 

 around our coasts, on seas adjacent to its breeding haunts, 

 especially in spring and summer. However, it may be met 

 with at other seasons of the year, and I have observed it in 

 small numbers in midwinter (January), in the Irish Channel. 



The curious figure of this bird as it skims over or dips 

 into the troughs of the waves, coupled with its wide spread 

 of wing, are points which serve to distinguish it easily 

 from the Guillemot or Razorbill which it resembles in size 

 and colour, and with which it often associates. At times it 

 may be seen swimming, and even 'rushing' under water 

 with outspread wings in an oblique direction, but I ques- 

 tion if it goes very deep, though an immersion may last 



1 Ray confounded young Shearwaters from the Isle of Man with the 

 young of the Puffin. Hence the origin of the generic name ' Puffinus,' 

 which has been adopted not only for this but for other Shearwaters, and 

 is, no doubt, misleading.
