“Tris hazel, bill black, feet whitish pink.” 
Very common on shady streams, especially where the 
current was swift, but not seen much in the open valley. Shy 
and very rapid and restless in their movements, flitting about 
generally in pairs from rock to rock with a curiously jerky 
action. The note is a shrill acid whistle and is constantly 
uttered.
