This handsome sparrow from the western United States was discovered frequenting a farm just a few miles north of Chambersburg on January 10, where it remained for at least the next ten days when these pictures were taken.  It proved quite cooperative and photogenic, along with the large group of White-throated and White-crowned Sparrows with which it has taken up residence.

 

Lark Sparrows, a common sight west of the Mississippi River, are casual in Pennsylvania, with a few dozen records over the years, but records are scarce in winter, with just two accepted occurrences before this one.
