Not obtained by Captain Raynolds' Expedition. 



Lieutenant Warren's Expediiion. — 8840, Lonp Fork. This single specimen, among Dr. 

 Hayden's collections, seems referable to typical aedon. 



The T. americanus of Audubon, a supposed species, which I doubtfully admitted in 

 1868, has since been shown by Mr. Allen and Mr. Mayuard to be inseparable from T, 

 aedon. It appears to represent simply rather northerly bred birds. The several extra- 

 liinital varieties of the species are not here considered ; our western variety is noted 

 under the next head.

 Hab. — Western United States, from Nebraska and Dakota to the Pacific. 

 Not obtained by Captain Raynolds' Expedition. 



Lieutenant Warren's Expedition.— i734r-3l,, 4737, 4138, 4741-43, Upper Missouri ; 5274-75, 

 Blackfoot country ; 5276, Fort Lookout ; 4739, Council Blufis ; 4740, Bald Island ; 4736 ; 

 North Plattfe. 

 . Later Expeditions. — 60688-9, Green River ; 62328-9, Idaho and Montana. 



Dr. Hayden's uumeroiis specimens attest the abundance of this variety 

 in the northwest. I found it to be numerous in the southwest ; and, in 

 fact, it is a common bird throughout the Middle and Western Provinces 

 of the United States, where it replaces its familiar Eastern represent- 

 ative. It is impossible to separate this form specifically from aedon ; it 

 is merely a little paler (grayer), while certain supposed peculiarities of 

 habit are shared by T. aedon in those unfrequented districts where its 

 ways have not been modified by contact with civilization. It is the 

 most numerous representative and the most uniformly distributed of the 

 Troglodytidce of the West. It is especially common in the scanty and 

 irregular belts of timber that border the streams of the great plains, 

 and occurs everywhere in the mountains up to about ;|.0,000 feet. Its 

 notes vary more or less at different localities, but everywhere it seems 

 to retain its pugnacious disposition, ajid its bold, inquisitive habits.
