Rufous-Crowned Sparrow

 The Rufous-Crowned Sparrow was photo at Yellowstone.
They are in long-tailed skulker of rocky, bushy hillsides and canyons areas.  More often heard then seen.

They have a rusty crown, white eye-ring, heavy dark whisker marks.  Their twit are a short jumble of notes.  They are found in the south-west part of U.S.
