Our other brave escorts were the white-crowned sparrows, which pursued the narrowing valleys until they were merged into the snowy gorges that rive the sides of the towering twin peaks. In the arctic gulches the scrubby copses came to an end, and therefore the white-crowns ascended no higher, for they are, in a pre-eminent sense, "birds of the bush." Subsequently I found them as far up the sides of Mount Kelso as the thickets extended, which was hundreds of feet higher than the snow-bound gorges just mentioned, for Kelso receives more sunshine than his taller companions, particularly on his eastern side. Brave birds are these handsome and musical sparrows. It was interesting to see them hopping about on the snow-fields, picking up dainties from the white crystals. How lyrical they were in this upper mountain valley! As has been said, for some unaccountable reason the white-crowns in the vicinity of Georgetown were quite chary of their music. Not so those that dwelt in the valley below Gray's and Torrey's peaks, for there they trilled their melodious measures with a richness and abandon that were enchanting. On reaching the snow-belt, though still a little below the limit of copsy growths, we saw our first pipits, which, it will be remembered, I had encountered on the summit of Pike's Peak two years before. In our climb up Gray's Peak we found the pipit realm and that of the white-crowned sparrows slightly overlapping. As soon, however, as we began the steep climb above the matted copses, the white-crowns disappeared and the pipits grew more abundant. At frequent intervals these birds would suddenly start up from the ground, utter their protesting "Te-cheer! te-cheer!" and hurl themselves recklessly across a snowy gulch, or dart high into the air and let their semi-musical calls drop and dribble from the turquoise depths of the sky. Did the pipits accompany you to the summit of the peak? I half regret to admit that they did not, but ceased to appear a good while before the summit was attained. This is all the more remarkable when it is remembered that these birds were extremely abundant on the crest of Pike's Peak, where they behaved in a "very-much-at-home" way.
