1920.] Birds of the Canary Islands. 109 



In tlie British Museum we liave only five skins^ four 

 collected in September 1886 at Wood's Holl, Mass., and 

 one in October of that year " off Gay Head.'^ 



P. k. fortunatus breeds in hundreds in the Canary Archi- 

 pelago — I believe on the coasts of all the islands, and 

 although I have not actually traced any records from 

 Gomera and Ilierro, there can be little doubt of its nesting 

 there. Its principal breeding-stations in the Archipelago 

 are all the outer islets (Ibis, 1911, pp. 267.. 268). I have 

 studied the habits of this species carefully and already 

 published my field-notes (Ibis, 1914, pp. 66-70, 80 et 267) 

 at some length. 



The main body of Canarian KuhFs Shearwaters arrive in 

 the Archipelago at the beginning of March, Savile Keid 

 noted many hundreds off Tenerife on the 19th of March, 

 1887 (Ibis, 1888, p. 80), They do not seem to commence 

 nesting in this month or during the early part of April, for 

 Meade-Waldo, who visited Graciosa on the 6th of April, 

 1890, reported that the Shearwaters had not yet arrived in 

 their breeding-holes (Ibis, 1890, p. 437 and MS. diaries). 

 The fishermen on Graciosa told nie that the birds arrived in 

 their nesting-holes during the latter part of April and 

 beginning of May " to clean their nests ^^ (Ibis, 1914, p. 68). 



Meade-Waldo saw them '' in swarms ^' off Garachico 

 (Tenerife) on the 15th of May, 1888 (MS. diaries). 



When I visited Graciosa from May 27-31, 1913, the 

 Shearwaters were all paired in their nesting-holes, but no 

 eggs had been laid. The birds commenced to lay the first 

 week in June, and by the second week in June nesting 

 seemed to be in full swing on all the outer islets (Ibis, 1914, 

 pp. 66-70, 80 et 87). The young are hatched in July. 



At the latter end of October the Shearwaters begin to 

 leave their nesting-places, and the main body finally leave 

 the islands in November (Ibis, 1914, p. 470). Holle thought 

 that they left the islands in September (J. f. 0. 1857, p. 314), 

 but many turn up in the neighbourhood of Gran Canaria 

 between the 1st of October and 17th of November (Ibis, 

 1912, p. 574). Meade-Waldo obtained thiee, and remarks
