MANX SHEARWATER. 



SHEARWATER PETRET. ISIANX PUFFIN. PETKEL IMANKS. 



PI,ATE CCXXXI. FIG, II. 



Procellaria pvffinus, . . Pennant. Montagu. 

 Procellaria anglorum, . . Jentns. Temminck. 



Puffinus anglonim, . . Fleming. Selby. 



These birds resort for the purpose of incvibation to 

 the highest grassy parts of small rocky islands and the 

 kindred shores of the mainland, as also to sandy places, 

 where they breed in burrows, going to a depth of about 

 two feet. The excavating of these appears to occupy 

 a considerable time. Both birds sit, and that so closely 

 as to allow themselves to be taken in the hand. 



They appear to be very variable in the time of laying, 

 from the end of May to the end of June. 



The nest is at most and best but a slight collection 

 of fern leaves and withered stems of other plants; fre- 

 quently none is formed, but the sand alone suffices the 

 bird. 



Only one egg is produced; it is large in size in pro- 

 portion to the bulk of the bird, perfectly white, and of 

 an oval form, but both ends obtuse. 



This egg was taken by the Rev. H. B. Tristram, in 

 Orkney. The plate is figured from it.
