533- Spinus pinus (Wils.)- 

 Pine Siskin. 



Summer resident and rather common, in the pine forests 

 and ranging from 5,flOO to 10,000 feet in elevation. Drexel 

 took this species at Fort Bridger in 1857. Grinnell has pub- 

 lished the following notes : "Abundant while migrating in the 

 Medicine Bow mountains. Though this species was noted 

 several times while in the park, it did not seem to be common 

 there. The birds were seen among the pines or else feeding 

 on the thistles below, after the manner of C. tristus (1875)." 

 The National Museum notes that No. 69866 was taken at Lar- 

 amie by Dr. J. S. Newberry. Merriam reports them from 

 Yellowstone park. 



Bond reports them from Cheyenne, where they have been 

 taken during migration, and Jesurun reports them from Doug- 

 las; Aiken found these birds in the vicinity of Sherman in 

 1870; Gary reports that he saw this species once or twice in 

 the vicinity of Newcastle. There is a single skin in the Uni- 

 versity collection that was taken by Gilmore in the northwest- 

 ern corner of Albany county. 



Passer domesticus (Linn.). 



European House Sparrow, 



Resident and gradually becoming more and more com- 

 mon over the state. In localities above 7,000 feet most of them 

 migrate for the winter. These birds have been in Cheyenne 

 for upwards of ten years, but have been kept down through 

 the persistent efforts of Mr. Frank Bond. In the winter time 

 when there are no other birds about he feeds them with wheat 

 soaked in a solution of strychnine and in a single day has 

 picked up over 180 dead birds. At Laramie they never have 

 been abundant, but each season there are a few more. At the 

 University buildings they have taken absolute possession and 

 driven away the blue birds, house finches,- phoebes and wrens. 

 In my opinion every effort possible, should, be put forth to ex-
