Birds of the Rockies

Water-Ousel
"Up, up, only
a few inches from
the dashing current"

After watching the tussle between ousel and water for a long time, I decided to take a peep at their nursery. In order to do this I was compelled to wade into the stream a little below the falls, through mist and spray; yet such humid quarters were the natural habitat and playground of these interesting cinclids. And there the nest was, set in a cleft about a foot and a half above the water, its outer walls kept moist by the spray which constantly dashed against them from the falls. The water was also dripping from the rock that over-hung the nest and formed its roof. A damp, uncanny place for a bird's domicile, you would naturally suppose, but the little lovers of cascades knew what they were about. Only the exterior of the thick, moss-covered walls were moist. Within, the nest was dry and cosey. It was an oval structure, set in its rocky cleft like a small oven, with an opening at the front. And there in the doorway cuddled the two fledglings, looking out at the dripping walls and the watery tumult, but kept warm and comfortable. I could not resist touching them and caressing their little heads, considering it quite an ornithological triumph for one day to find a pair of water-ousels, discover a nest, and place my finger upon the crowns of the nestlings.

Scores of tourists visited the famous falls every day, some of them lingering long in the beautiful place, and yet the little ousels had gone on with their nest-building and brood-rearing, undisturbed by human spectators. I wondered whether many of the visitors noticed the birds, and whether any one but myself had discovered their nest. Indeed, their little ones were safe enough from human meddling, for one could not see the nest without wading up the stream into the sphere of the flying mists.

The natural home of Cinclus mexicanus is the Rocky Mountains, to which he is restricted, not being known anywhere else on this continent. He is the only member of the dipper family in North America. There is one species in South America, and another in Europe. He loves the mountain stream, with its dashing rapids and cascades. Indeed, he will erect his oven-like cottage nowhere else, and it must be a fall and not a mere ripple or rapid. Then from this point as a centre—or, rather, the middle point of a wavering line—he forages up and down the babbling, meandering brook, feeding chiefly, if not wholly, on water insects. Strange to say, he never leaves the streams, never makes excursions to the country roundabout, never flies over a mountain ridge or divide to reach another valley, but simply pursues the winding streams with a fidelity that deserves praise for its very singleness of purpose. No "landlubber" he. It is said by one writer that the dipper has never been known to alight on a tree, preferring a rock or a piece of driftwood beside the babbling stream; yet he has the digits and claws of the passeres, among which he is placed systematically. He is indeed an anomaly, though a very engaging one. Should he wish to go to another cañon, he will simply follow the devious stream he is on to its junction with the stream of the other valley; then up the second defile. His flight is exceedingly swift. His song is a loud, clear, cheerful strain, the very quintessence of gladness as it mingles with the roar of the cataracts.

Farther up Ute Pass I found another nest, which was placed right back of a cascade, so that the birds had to dash through a curtain of spray to reach their cot. They also were feeding their young, and I could see them standing on a rock beneath the shelf, tilting their bodies and scanning me narrowly before diving into the cleft where the nest was hidden. This nest, being placed back of the falls, could not be reached.

In Bear Creek cañon I discovered another inaccessible nest, which was placed in a fissure at the very foot of the falls and only an inch or two above the agitated waters. There must have been a cavity running back into the rock, else the nest would have been kept in a soggy condition all the time.

Perhaps the most interesting dipper's nest I found was one at the celebrated Seven Falls in the south Cheyenne Cañon. On the face of the cliff by the side of the lowest fall there was a cleft, in which the nest was placed, looking like a large bunch of moss and grass. My glass brought the structure so near that I could plainly see three little heads protruding from the doorway. There were a dozen or more people about the falls at the time, who made no attempt at being quiet, and yet the parent birds flew fearlessly up to the nest with tidbits in their bills, and were greeted with loud, impatient cries from three hungry mouths, which were opened wide to receive the food. The total plunge of the stream over the Seven Falls is hundreds of feet, and yet the adult birds would toss themselves over the abyss with reckless abandon, stop themselves without apparent effort in front of their cleft, and thrust the gathered morsels into the little yellow-lined mouths. It was an aerial feat that made our heads dizzy. This pair of birds did not fly up the face of the falls in ascending to the top, as did those at Rainbow Falls, but clambered up the wall of the cliff close to the side of the roaring cataract, aiding themselves with both claws and wings. When gathering food below the falls, they would usually, in going or returning, fly in a graceful curve over the heads of their human visitors.
