White-throated Sparrow, Louisville, Kentucky, 10/11/2020.

Visits my area only in the winter. The White-throated Sparrow species has 4 sexes, male/female with white strips on the head, and male/female with tan stripes on the head. This individual appears to be of the tan-striped variety. They can only mate with the opposite colored stripes.
