The Birds of El Paso County, Colorado 601 



to a nest found on Mount Manitou, July 6, 1872, containing 

 4 young; this was in a tree 2j^ feet from the ground. War- 

 ren observed it at Lake Moraine, September 2, 1905. Aiken 

 noted it July 9 and 10, 1899, as common about Strickler Tun- 

 nel and at intervals down to the Half- Way House. His notes 

 say : "Song not as musical close to as at a little distance. I am 

 reminded by the song of a musician, idly striking chords on a 

 harp and listening after each chord for the echoes to die away." 



Planesticus migratorius propinquus. Western Robin. 



Summer resident; common. A few frequently spend the 

 winter. The first spring arrivals sometimes come as early as 

 February 25, but they do not become common until some time 

 in March, usually the first or second week. The majority leave 

 in October. 



As stated above a few Robins frequently winter with us. 

 The winter of 1904-5 there seemed to be a good many about 

 Colorado Springs, and they were often noted in the town 

 from November through the winter months and until the 

 spring migrants came to swell their numbers. One was seen 

 January 20, 1905, in a sheltered gulch in the foothills at about 

 7,000 feet. They do not seem to be afraid of the cold for they 

 have been seen in zero weather. Aiken saw Robins at the 

 Strickler Tunnel, 11,500 feet, April 22-23, 1899, and was told 

 they had just arrived. 



This species is found all over the County, and as just 

 stated, ranges high into the mountains, and breeds wherever 

 found. About Colorado Springs they pair in April and build 

 'immediately. Monument Valley Park had many nests in 1913, 

 10 being discovered in a small area; some of the young had 

 left the nest by June 1. A young bird which was banded in 

 a nest May 27, 1913, flew through glass in a greenhouse of 

 the Pikes Peak Floral Co., June 23, 1913, and was killed.
