hanging roofs of small caves. The song is heard not 
only in the breeding season but in the middle of winter 
on a fine day, especially among the rocks of the Garden 
of the Gods, where it is nearly always to be met with. 
Further south, in Texas and Mexico, the Cafion-Wren 
is a more familiar bird, often settling about houses and 
singing from the chimney tops, but except in the case 
of an individual seen by Burnett “in a yard stacked with 
cement building blocks” in Longmont, it appears to 
avoid the haunts of man in Colorado. 
The only definite nesting record in Colorado is that of 
Minot. He found a nest near Manitou on June 8th, 
1880. It was placed in a niche in the roof of a cave 
about ten feet above the ground, and so narrow was the 
entrance that he was unable to put his hand in ; it was 
necessary finally to obtain the help of a mason to knock 
the slab away. The nest itself was made of twigs, very 
roughly and loosely put together with a lining of a thick 
felt of down and feathers, held together with a few plant 
stalks. The eggs, five in number, were white, with a rosy 
tinge before being blown, delicately speckled, chiefly 
towards the larger end, with reddish-brown. They 
measured “75 x ‘55. 
Dille has recently given a rather different account, 
at least as far as the date is concerned ; he located a nest 
in a sheltered crevice on a sixty-foot cliff in the foothills 
of Boulder co. By means of a rope an investigation 
was made on April 4th, when the nest was found to 
be completed, and to contain three eggs; but it was 
not further disturbed. Brunning mentioned to Dille 
three other nesting sites of the Cafion-Wren in the 
immediate neighbourhood, and stated that the bird 
arrived only about the end of November, and left again 
in spring, I presume after nesting was finished.
