FFTD Bonus Brown Creeper 8-21-14

On a recent hike a bird watcher with
binoculars pointed out a "brown
creeper" which turned out to be a
sparrow like bird that can only walk
up a tree because of the anatomic
form of its feet. If it tries to walk down
it falls because its feet can not
hold it up. It often passes nuthatches
that are walking down the tree as it
walks up using its tail for balance.
