The other day my husband and I were watching the birds feeding outside of our window when a snake who was apparently hanging out in our gutter grabbed a tufted titmouse. In the first photo, taken from inside the house, you can barely make out the snake. In the second photo, you can see no sign of the snake, but he was clearly holding on to his prey. Shortly thereafter, the bird was pulled into the gutter to serve as the snake's dinner.
Definitely one of the strangest sights we've seen!
