Saturday (White-throated) Sparrow

White-throated Sparrow fun fact (courtesy of the Cornell Lab of Ornithology’s All About Birds website):

“Although they look nothing alike and aren’t particularly closely related, the White-throated Sparrow and the Dark-eyed Junco occasionally mate and produce hybrids. The resulting offspring look like grayish, dully marked White-throated Sparrows with white outer tail feathers.”
