Thryomanes bewicki bairdi. Baird's Wren. 



But one record from El Paso County, a specimen taken by 

 Aiken at Colorado Springs, May 1, 1879. 



Troglodsrtes aedon parkmani. Western House Wren. 



Summer resident; common. Arrives the first week in 

 M^, earliest date April 24, 1898. Leaves in September, the 

 lafpst date being September 25, 1907. 



, Probably found all over the County, ranging up to timber- 

 line, and abundant wherever found, and breeding everywhere. 

 Aiken found a nest with 7 fresh eggs in a cavity in a rock 

 ledge near Palmer Lake, June 26, 1907. Their favorite nest- 

 ing places are natural cavities in trees or old woodpeckers' 

 holes, but they will use almost any hollow they can find. 



Telmatodytes palustris plesius. Western Marsh Wren. 



Summer resident; not common. 



Arrives in April. A Marsh Wren seen by Aiken near 

 Skinner's April 16, 1899, was probably of this form. One was 

 shot not far from the same locality by Allen and Brewster 

 April 22, 1882. The scarcity of records is due to the scarcity 

 of suitable ground in the vicinity of Colorado Springs. That it 

 breeds in the County is only presumptive ; there are no records. 



Telmatodytes palustris iliacus. Prairie Marsh Wren. 



Winter resident ; moderately common in suitable localities. 

 Aiken saw several at Skinner's, and took one, January 15, 1908, 

 which was examined by Oberholser and referred to this sub- 

 species. Probably all winter residents are visitors from the 

 north and should be so classed. 



Certhia familiaris montanus. Rocky Mountain Creeper. 

 Resident in the mountains ; not common. 

 The Brown Creeper is not at all common in El Paso
