OFFERTO DA MERLIN
Unmistakable plump passerine. Slaty-gray overall with a browner head. Juveniles are slightly paler below than adults. Forages for invertebrates by walking underwater. Inhabits fast-moving rocky streams in western North America, from Alaska to Panama. Often nests under bridges. Unique shape, behavior, and strict habitat preferences make American Dipper unlikely to be confused with any other species.
