Lots of excitement this morning!
The barn swallows that nest under my carport were raising Cain so I looked out to see what was going on.
A snake (about 2' long I would guess) was after the eggs, reaching down from the ceiling from between the vinyl siding!
I can't say what species it was because I hadn't put my glasses on yet.
Normally I let nature take its course but the swallows get special consideration so I discouraged it with a broom. The reptile is still in the siding and I hope it finds lots of prey that doesn't eat mosquitoes.
