The presence of practically the same avian fauna on both sides of the great range suggests some speculations as to their movements in the migrating season. Do those on the western side of the mountains travel over the towering summits from the eastern plains? Or do they come up from their southern winter homes by way of the valleys and plains west of the range? Undoubtedly the latter is the correct surmise, for there were birds at Glenwood that are never known to ascend far into the mountains, and should they attempt to cross the Divide in the early spring, they would surely perish in the intense cold of those elevated regions, where snow often falls even in June, July, and August. One can easily imagine some of the eastern and western residents meeting in the autumn on the plains at the southern extremity of the mountain range, dwelling together in some southern locality throughout the winter, and then, when spring approaches, taking their separate routes, part going east and part west of the range, for their breeding haunts in the North. More than likely they do not meet again until the following autumn. There are individuals, doubtless, that never catch a glimpse of the western side of the great American watershed, while others are deprived of the privilege of looking upon the majestic panoramas of the eastern side. What has just been said applies, of course, only to those species that prefer to dwell in the lower altitudes. There are other species that find habitats to their taste in the most elevated localities, ranging at will in the summer time over the bald summits in the regions of perpetual snow. Among these may be mentioned the brown-capped leucostictes, the American pipits, the ravens, and Brewer's blackbirds. These species will often have the privilege of looking upon the scenery on both sides of the range, and you and I can scarcely repress a feeling of envy when we think of their happy freedom, and their frequent opportunities to go sightseeing. While taking an early morning stroll along one of the streets of Glenwood, I caught sight of a new member of the phoebe family, its reddish breast and sides differentiating it from the familiar phoebe of the East. Afterwards I identified it as Say's phoebe, a distinctly western species. Its habits are like those of its eastern relative. A pair of Say's phoebes had placed their nest on a beam of a veranda, near the roof, where they could be seen carrying food to their young. My notes say nothing of their singing a tune or even uttering a chirp. This was my first observation of Say's phoebe, although, as will be seen, I subsequently saw one under somewhat peculiar circumstances.
