and took it to the ship as I was going homeward. Not 

 many days afterwards the little bird began to sing, 

 and shortly after I arrived in Holland it began to moult 

 and acquired the black cap and rosy tinge on the feathers 

 of the lower back and sides, and also the whitish cheeks. 

 The bill also changed from yellowish horn-colour into 

 jet-black. 



After having worn this dress a few months the bird 

 moulted again, and I was surprised to find that it again 

 acquired the sober, nearly uniformly buflf dress that it had 

 worn when I bought it in Santos. The bill also lost its 

 black colour. 



Since that time the little bird has moulted regularly from 

 one dress into the other, generally twice a year, the l)lack cap 

 and bill and other ornamental colours forming the breeding- 

 dress. The bird is in full song then. The song is very 

 pleasant and has some remarkable notes. , 



Although such a small mite, it is very aggressive, and 

 will not suffer other birds in its cage or even in a large 

 aviary.

Introduction. 



For several years before the war I was engaged upon a 

 work embodying all that is known of the Birds of the 

 Canary Islands. For this purpose I have had translated 

 almost every foreign work bearing on the subject, in addition 

 to which I have consulted the many English papers written 

 by British ornithologists who have visited the islands and 

 studied the Ornis of the Group. 



Every year from 1908 to 1913 I visited the Archipelago 

 myself and made various expeditions, both privately and on 

 behalf of the Natural History Museum, to gain a thorough
