102 BIRDS OF THE PUBLIC GARDEN 



1908, in each instance a single bird. In 

 May the visits have occurred between 

 May 7 and 30. 



A little flock numbering from six to eight 

 birds has been seen but four times. The 

 occurrences of a single bird far outnumber 

 those of two or more birds. Not uncom- 

 monly the lone Goldfinch has been in song. 



Fewer individuals have been recorded 

 in the autumn, but the species regularly 

 reappears then and has furnished many 

 November as well as October records, the 

 latest birds being a little flock of four pre- 

 sent on November 22, 1903. 



43. PINE SISKIN 



Spinus pinus 



In 1907 and 1908 only has the Pine Siskin, 

 or Pine Finch, been recorded in the spring 

 in the Garden. On May 20 of the former 

 year a single bird was heard calling hi flight, 

 and on May 25 one was seen perching and 

 singing. In 1908 a Siskin appeared on 

 May 12, when a very large general migra- 

 tion-flight manifested itself in the Garden.
