Chickadees out in full force this calm, snowy morning, two nights and one day into this heavy snowfall.

A mystery bird came to the oak trunk and clung upside down there, closely followed by a female Downy Woodpecker with its smart black and white back.

The mystery bird is about twice the size of the chickadees, a little smaller than the woodpecker. Bigger than the nuthatches that frequent this area. Creamy buff breast and darker, greyish back. Shaped like a nuthatch or woodpecker with their short stubby tails.

The Downy meandered up the ant-sheltering oak trunk for a while, hunting, while the mystery bird just hung out, upside down, sheltering on the leeward side of the trunk.

A passing chickadee stopped at the tree and watched the woodpecker hopefully for a while.
