VESPER SPARROW 103 



In four of the years of my observation 

 Siskins have been recorded in October. In 

 1 90 1 two Httle 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 21a 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.
