202 BIRDS OF THE ROCKIES

 appearance. On the wing, the birds, as I afterwards 

 observed, often chirped a little lay that bore a close

 the American goldfinch. Indeed, a number of their 

 notes suggested that bird, as did also their manner of 

 flight, which was quite undulatory. The birds were the

 need of the cognomen " western " prefixed to his name 

 when he takes it into his wise little head to make his 

 abode in the Rocky Mountains. 



The reader will perhaps recall that a flock of pine 

 siskins were seen, two years prior, in a patch of pine
