On May 4, 1893, I found a nest containing four eggs and a 

 female that evidently had died while sitting. All were cold. 



In the spring of 1898 I transferred three young linnets from the 

 nest where they had just hatched to the nest of a pair of domestic 

 canaries whose young were of about the same size. The canaries 

 showed no objection to this sudden addition to their family, and 

 reared all successfully. Late in the summer two of the young lin- 

 nets began to sing in low tones. To my surprise, their song was 

 entirely copied from that of their foster parent, though of only 

 about half its extent. Early in the summer of 1899, these birds 

 were liberated. Their song then consisted of about one-half of the 

 song of the house finch, followed by several trills from the song 

 of the canary and for several months after this they could be dis- 

 tinguished by it. What finally became of them, I do not know. 

 Birds which have been reared in a cage have the usual red of the 

 plumage replaced with yellow. Caged adults also become yellow 

 after moulting. 



Astragali7ius tristis salicamans. Willow Goldfinch. 



I have not seen this bird at Los Gatos in summer, although it 

 occurs there in considerable numbers in winter. It is not rare at 

 Palo Alto at any season. 



Asiragalinus psaltria. Green-backed Goldfinch. 



This beautiful goldfinch breeds very abundantly in all parts of
