Female white-breasted Nuthatch (Sitta Carolinensis)
Active and agile, nuthatches are often seen traveling upside-down down a trunk or hanging sideways on a feeder. Their name comes from their habit of inserting seeds (or nuts) into tree bark and then banging them with their beaks to "hatch" the tasty insides.
Nuthatches can become quite tame, though a bit more wary of humans than chickadees are.
