CANON WREN. 
717a. Catlierpes mexicanus conspersus. 5 y 2 inches. 
Range. —Rocky Mountain ranges, from Colorado to Mexico, 
breeding throughout its range. As he is gathering his supply 
of food among the huge boulders and in the large rocky 
canyons, where he makes his home, you will, at short inter¬ 
vals, hear his loud joyous song, a song that puts to shame 
that of his largest relative of the plains. They build their 
nest of small sticks, leaves, grass and feathers, which is 
placed in the crevice of some rock, either down near some 
swiftly running mountain stream or high up in the cliffs 
above. Their three to five eggs are white, with spots of brown 
and lilac well covering the under color (.72 x.52). 
VIGOR WREN. 
719a. Thryomanes bewicJci spilurus. 5 inches. 
Range. —Coast regions of California. These are active and 
restless little birds. Eating and singing, and singing and 
eating is all this life holds for them. Nesting in bird boxes, 
holes in trees, in sheds, or almost any locality in which to 
place their six eggs (.65x.50).
