Flicker for Flickr
The male Northern Flicker has a black moustache, which the female lacks...that's appropriate, isn't it? There are two varieties/groups: Yellow-shafted and Red-shafted. This is the Yellow-shafted Flicker, which is fairly common in our area. It's a fairly large woodpecker, about 12 inches (30.5cm) iin length.
Seen at Lake Erie Metropark, Michigan USA.
