the Tubinares in the North Atlantic Islands. 473 



General Conclusions. 



A glance at the following records will show that this 

 Shearwater is not by any means universally distributed 

 amongst the several groups o£ islands. In fact its breeding 

 range is probably quite local. In the Azores we find that it 

 is decidedly arare^ though probably a regular^ breeding bird. 

 In the Madeira Group it breeds on ail the large islands^ and 

 this may be considered its stronghold in the north Atlantic. 

 Kecords from the Salvages are not by any means satisfactory, 

 nor are those from the Canary Group, while in the Cape 

 Verde Islands this bird is altogether absent. 



Pvffinus ji- pyffinus leaves the islands during the winter 

 months — departing in October or November and returning 

 again at the end of February or early in March. The 

 breeding season commences almost at once and continues 

 until August, which is the latest month in which young-in- 

 down have been taken. May and June are evidently the 

 principal breeding months.
