Hairy Woodpecker vs Downy Woodpecker
Its in the same spot as a female Downy Woodpecker I photographed a while back...
These two birds are good examples of Convergent Evolotion, but more interestingly, offer great basic lessons in birding.
Birding Videos from Cornell: (The size/shape video uses these woodpeckers in their discussion)
Great resource on comparing Hairy vs Downy Woodpeckers
