Breeding range in the Azores. 

 IMentioned by every writer from Droiiet onwards who has 

 ever studied the avifauna of this group. According to the 

 various accounts P. k. flavirostris breeds on all the islands 

 and is particularly numerous in the central group. Appa- 

 rently the birds only begin to arrive at their breeding haunts 

 early in March^ and even as late as May 30 there are many 

 nesting-places still empty. Godman, however^ found the 

 birds breeding at the end of May. It would seem that the 

 various colonies do not all commence nesting-operations at 

 the same time. By the middle of June all the birds have 

 laid. Mr. Ogilvie-Grant^s account of these birds in the 

 Azores is by far the best puljlished^ but he had, unfortu- 

 nately, left the island before the young were hatched. 



Breeding range in the Madeira Group. 



Breeds on all the islands and rocks of this group. Par- 

 ticularly abundant on the Desertas and the island of Porto 

 Santo. 



They appear in Madeira at the end of Fel)ruary and 

 beginning of March, and although hundreds are seen at sea 

 in the neighbourhood of the islands throughout April, they 

 do not seem to commence laying in this month. By May 4 

 many birds are paired, and doubtless a few early layers are to 

 be found soon after this date. Padre Schmitz considers the 

 middle of June the best season for finding their eggs^although
