This morning I was pleasantly surprised to find the white over blue banded Song Sparrow singing in the tree in the yard. The last time I saw him(?) was 10 April, and I’m guessing at that point he departed for points north to nest. As I observed, I had the impression that he may have been establishing a territory of sorts – in particular, letting a Song Sparrow in a neighboring yard know that this was going to be his winter home. I haven’t noticed any Song Sparrows in my yard (at least not with any consistency) since he left in April.
