A Flicker is in the woodpecker family and spends most of it's feeding time on the ground or on the side of a tree eating bugs.
(or at my suet)
The undersides of the wing and tail feathers are bright yellow, for eastern birds, or red, in the western species.
You can see the yellow under her tail feathers.
This is a male who will become a lot bluer as spring arrives.
The females have almost no blue on them right now.
As you can tell by the snow,
these pictures were taken several weeks ago..
