Went out to my GH this AM to start more seeds, peppers.
Now and hen I hear the sound of snow sliding off the roof, but out of the corner of my eye I caught a movement.
WOOO do I have a varment in here ? Well I sat still for a minute and then saw this...
Well I have no idea how he got in, I guess he drinks water from the trays I have the plants sitting in.
I ground up some rabbit pellets for him, don't know what he eats.
Can any one ID this bird ? Sparrow, Chickadee ?
