A plain gray songbird that feeds underwater in fast mountain streams.
Gray and compact, the American dipper does not look remarkable until it moves. Zion National Park names the Virgin River and its tributaries as its home, and the bird, also called the water ouzel, spends its whole life foraging in and under moving water. It bobs on streamside rocks, wades, swims and dives, and the park says it can use its wings to swim up to 20 feet underwater.
The food is the key. Zion lists stoneflies, mayflies, caddisflies and their larvae, small fish and snails on the menu, picked from under rocks and between gravel. A transparent inner eyelid helps it see underwater. A dipper is therefore a bird of clean, flowing streams with a steady insect supply, and a good reason to watch a stream as a living system rather than as scenery.
Look from a settled spot on an established bank or trail and let the bird come into view; its bobbing on wet stones is the giveaway. Stay off fast water and away from banks where it may be nesting. This profile rests on the Zion account, so it does not claim the dipper for every Utah stream.
Plain gray, rounded songbird that bobs on stream rocks and dips under the water.
Watch from established banks and trails; do not wade into fast water or approach nest sites.

A paddle-tailed rodent whose feeding and construction can transform a stream into a complex wetland.

An upturned bill, blue-gray legs and a sweeping feeding motion make this wetland shorebird especially distinctive.

A large white migrant whose family groups link Utah's wetlands with Arctic nesting country.

The largest member of the deer family in Utah, at home where northern mountain forest meets water.
