On June 22nd, I observed these two sparrow-like birds at Gettysburg, PA.
There were very small and quite, tame.
In short flight (one foot or so) they had light colored outer tail feathers.
Breast and flanks are lightly striped
They may well be immature birds, but are obviously brightly marked.
They made no vocalizations.
