CAÑON WREN.
717a. Catherpes mexicanus conspersus. 5½ 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 intervals, 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 × .52).
