He was just hanging out near my front door when the Mrs. and I got home. It's an Eastern Rat Snake, but around here they just call them "black snakes".
Black snakes are pretty harmless, really. They go around eating rodents, other reptiles, birds, and amphibians. Oh, and according to the locals they eat Copperheads.
Why yes, Mr. Black Snake, you can hang around!
I just wonder if he's scared off all the hummingbirds. We've had a fair amount coming and sipping at our feeders, as well has entire flocks of finches, cardinals, jays, etc at the feeders in our front yard. That's probably why the snake was hanging around; he was looking for a meal.
