460 Birds of Colorado 



Distribution. — Breeding from Alaska to Oregon, and perhaps south 

 to the mountains of Lower Cahfomia, and east to western Colorado ; 

 in winter south to western and central Mexico as far as Guatemala. 



Townsend's Warbler is apparently a rare bird in Colorado, and 

 there is no definite record of its breeding within the State. It was 

 taken by Aiken, according to Henshaw, at Conejos, August 26th, 

 and at the mouth of the Navajo Creek in Archuelta co., September 

 11th, in the south of the State ; Lowe says that it is abundant in the 

 Wet Mountains in the fall at elevations of 7,400 to 10,000 feet ; while 

 Cooke states that one example was seen by Captain Thorne at Fort 

 Lyon on May 26th, 1883, and Chapman notes its arrival at Loveland 

 on May 11th, 1889. The only authority for its breeding is that of 

 Drew, who gives no further details. Gary reports that he shot a male 

 August 24th, 1906, on the Snake River, twenty miles west of Bagg's 

 Crossing, while on its southward migration in company with other 

 Warblers. 



Habits. — This Warbler frequents the highest trees, 

 and is very active in its movements after insects, so 

 that it is difficult to obtain. According to Henshaw, 

 it affects the firs and spruces and shuns the true pines. 

 Its note is described as a simple " Tsip." 



The only well-authenticated eggs known appear to 

 be a set taken at Vancouver by Walter Raine, and 

 described by J. L. Childs in Chapman's Warblers.
