American Dipper

This American Dipper has been sitting patiently in my blog queue since 28 May 2921, when Erika and I photographed it at our dipper spot, Tumwater Falls Park in Olympia. Dippers are identified by their frequent bobbing up and down and by their often jumping into turbulent, freezing water. The white spots at the end of the flight feathers indicate this bird is relatively recently hatched.
Dippers often blink their white eyelids, especially while they are bobbing. Both the upper and lower eyelids are adorned by narrow, white feathers. This blinking must have some behavioral significance, but I am not sure what it is. Perhaps the white flashes produce some sort of territorial advertising to other dippers.
