1920.] Birds of the Cunury Islands. Ill 



my paper on my expedition to the eastern Canary Islands 

 (Ibis, 1914, pp. 264-266). 



P. a. baroli appears to arrive in the Canary group at tlie 

 end of January or early in February. At the end of 

 February it seems to commence breeding in Tenerife — a 

 very early date; but the breeding-time seems to vary in the 

 different nesting-colonies : at any rate, I have taken eggs as 

 late as 8 June on the outer islets. February, March, and 

 April I believe to be the true breeding-season, prolonged in 

 certain colonies until the end of the first week in June. By 

 the end of that month I believe the birds have all reared 

 their young in the Canary Archipelago, and they probably 

 leave the islands soon afterwards. We have no records of 

 tlie birds being seen in this group from the beginning of 

 July until the end of January, although we have no data 

 to show when they actually take their departure. 



The following notes are arranged under the heading of 

 the different islands in which they breed. I have already 

 noted that considerable diversity seems to be shown in the 

 breeding-time of the various colonies. 



Gran Canaria. 

 Only one record from this island. Meade-Waldo found a 

 pair breeding near Arncas; unfortunately this record was 

 erroneously published by me under Bvhveria buJiveri (Ibis, 

 1912, p. 574). 



Tenerife. 



First mentioned by Webb and Berthelot from this island 

 — they mention a bird taken by the Orotava fishermen in 

 February 1829, and include the species only as " De passage 

 accidentel,^' remarking that " La propagation de ce Puffin est 

 encore inconnue,"' which proves that the authors had never 

 found it breeding in the Archipelago (Orn. Canarienne, 

 pp. 43, 44) . 



Savile Reid mentions a bird from Orotava picked up on 

 the shore on the 15th of March, 1887 (Ibis, 1888, p. 81),
