stay on Graciosa, from May the 27th till June the 7th, a 

 small but deserted colony was pointed out by the fishermen, 

 who assured me that the birds had already bred and departed. 

 They told me that these Shearwaters came in j\Iarch and had 

 left Graciosa before the end of May, but that I should still 

 find a few on Montaiia Clara ; this, sure enough, turned out 

 to be the case, for we had not been on this island a day 

 before the fishermen brought me several birds, which is proof 

 enough that they knew which species they were talking 

 about ! 



From the few definite dates which we have, it appears 

 that the bird breeds at different times on the different 

 islands — February, March, and April being the usual months 

 in Tenerife and perhaps on Graciosa, while, sti^ange to say, on 

 Montai3a Clara, which is only distant from Graciosa about 

 one-and-a-quarter miles, the birds seem to breed slightly 

 later. This bears out my theory, already expressed ; that 

 the several nesting colonies breed quite independently of one 

 another. There are no records of this bird being seen in 

 the Canary Islands during the summer.

Range beijond the North Atlantic Islands. 



The extent of the range of this Shearwater beyond the 



Cape Verde Archipelago is not known. It probably does 



not wander very far. It is represented in the Bahamas, 



West Indies, and Bermudas, by typical Puffinus Iherminieri
