The Ouzel seldom swims more than a few yards on the surface, for, not
being web-footed, he makes rather slow progress, but by means of his
strong, crisp wings he swims, or rather flies, with celerity under the
surface, often to considerable distances. But it is in withstanding the
force of heavy rapids that his strength of wing in this respect is most
strikingly manifested. The following may be regarded as a fair
illustration of his power of sub-aquatic flight. One stormy morning in
winter when the Merced River was blue and green with unmelted snow, I
observed one of my ouzels perched on a snag out in the midst of a
swift-rushing rapid, singing cheerily, as if everything was just to his
mind; and while I stood on the bank admiring him, he suddenly plunged
into the sludgy current, leaving his song abruptly broken off. After
feeding a minute or two at the bottom, and when one would suppose that
he must inevitably be swept far down-stream, he emerged just where he
went down, alighted on the same snag, showered the water-beads from his
feathers, and continued his unfinished song, seemingly in tranquil ease
as if it had suffered no interruption.

The Ouzel alone of all birds dares to enter a white torrent. And though
strictly terrestrial in structure, no other is so inseparably related
to water, not even the duck, or the bold ocean albatross, or the
stormy-petrel. For ducks go ashore as soon as they finish feeding in
undisturbed places, and very often make long flights over land from lake
to lake or field to field. The same is true of most other aquatic birds.
But the Ouzel, born on the brink of a stream, or on a snag or boulder
in the midst of it, seldom leaves it for a single moment. For,
notwithstanding he is often on the wing, he never flies overland, but
whirs with, rapid, quail-like beat above the stream, tracing all its
windings. Even when the stream is quite small, say from five to ten feet
wide, he seldom shortens his flight by crossing a bend, however abrupt
it may be; and even when disturbed by meeting some one on the bank, he
prefers to fly over one's head, to dodging out over the ground. When,
therefore, his flight along a crooked stream is viewed endwise, it
appears most strikingly wavered--a description on the air of every curve
with lightning-like rapidity.
