VESPER SPARROW 103 



In four of the years of my observation 

 Siskins have been recorded in October. In 

 1901 two little flocks of three and five birds 

 respectively paid a fleeting visit on Octo- 

 ber 26 and 27. In 1906 a single bird was 

 recorded on October 17 and 22. In 1907 a 

 flock of ten birds lit in a tree-top on Octo- 

 ber 19, and again on October 21 a flock of 

 six birds was noted. On October 25 one 

 bird made its presence known by giving its 

 characteristic call. And in 1908 the mi- 

 gration movements of the species were 

 manifest up to November 12, two birds 

 appearing on October 10, twenty on Octo- 

 ber 14, a flock which numbered quite a 

 hundred passing over on October 18, and 

 scattered birds thereafter, one occasionally 

 coming into a tree, feeding and calling.
