Couldn't find a tree sparrow at the feeder (south of Crossville), only a Lincoln's Sparrow joining the 2 Fox Sparrows, Swamp Sparrow and assorted Song, Field, and White-throated Sparrows this morning (Mar. 4). I'm assuming this is the same individual Lincoln's Sparrow that was here on Jan. 6 and 7 during the cold weather then. The Fox Sparrows have tended to stay away unless the weather has been bad.
