Ornis of this group, the results of whose work I have here 

 attempted to collaborate. 



It is at any rate the nrst complete List of the Birds of 

 the Canary Islands which has ever appeared in the English 

 language, though Meade-Waldo's list published in 1893, 

 comprising only birds which came under his own notice, 

 came very near to accomplishing this end. 



Terms to be used. 



Residents. Birds generally found in the Canary Islands 

 throughout the year are included in this category ; 

 it includes those which regularly breed in the Archi- 

 pelago and which are not migratory in any way except 

 perhaps between the islands. 



Partial Residents. Birds which are usually resident and 

 breed in the islands, but which have their numbers 

 augmented by fresh arrivals at certain seasons. 



Summer Visitors. Birds which are found nesting regularly 

 in the Canary Islands, but do not remain throughout 

 the winter in the xlrchipelago. 



Winter Visitors. Birds found in the Canary Islands during 

 the winter only, and which have only exceptionally 

 been known to breed in the Archipelago. 



Birds of Passage. Birds Avhich pass regularly through the 

 islands during the spring and autumn migration 

 periods. 



Annual Visitors. Birds which visit the Archipelago annually 

 l)ut at no fixed season of the year and which have 

 not been known to breed in any of the islands. 



Occasional Visitors. Birds which do not occur regularly in 

 the Archipelago every year but which have been 

 recorded from time to time, almost invariably during 

 the migration period. None have been known to 

 breed in the islands. 



Rare Visitors. Birds which have occurred in the islands 

 on two or three occasions only, sometimes singly 

 after violent storms, but usually in company Avith 

 other species during migration.
