American Dipper are commonly found perched on a rock in the middle of a rushing mountain stream. A stocky, medium-sized gray bird (5.5-8 in), they're constantly bobbing up and down. They catch aquatic insects by diving, swimming, or walking in streams. An extra eyelid enables them to see underwater.
Dipper can be found year-round in fast-moving, unpolluted mountain streams in northwestern North America.
Did you know? Dipper are able to survive in cold water during the winter due to their low metabolic rate, extra oxygen-carrying capacity in their blood, and a thick coat of feathers.
