The Narrows - Water Ouzel
I spot a Water Ouzel, also known as the American Dipper.
I first saw one in Glacier National Park years ago and was fascinated as I watched the bird dip below the surface of a fast moving stream while feeding.
"With the benefit of several unique adaptations such as an inner protective eyelid and an extra layer of downy feathers, the ouzel dives into cold, often turbulent rivers and streams, swimming, and walking along the bottom of the river. It uses the pressure of water on its wings and tail to help keep it down while it searches for insect larvae and other small animals on which to feed. Both the wings and tail are short, the beak is fairly short and straight, and the general color of the bird is a slate gray. When on shore, it has a custom of “dipping” that easily distinguishes it from any other bird along the river."
