I saw the change too. Now the bird house was on the porch and the snake was in the rafters of the house. Either way is was a chicken snake or a rat snake, both harmless, but not a rattle snake.
I suppose I’ve dealt with more snakes than many folks. I’ve never seen a rattler climb much of anything, let alone bird house poles and rafters. Moccasins will crawl out a limb and bask, but horizontal trees are easy.
Someone is covering butt here, and not very good at it.
