Northern Flicker

Ther northern flicker is a large North American woodpecker, but most of the time you won't see it drumming on trees. It's favorite food is ants, and it drums into the earth to dig up ants, beetles, and other insects. It's got a long tongue to lick up them up.

This is the eastern or "yellow-shafted" form of flicker, so named for the yellow shafts on some of it's feathers.  The western form is red-shafted.
