A close-up of his front show his perfect colouration. I think he is such a beauty.
The black lines on his face indicate this fellow is a male - a moustache, if you will. The female has all the same markings but this one.
In the next two shots, you can see the yellow underneath his tail feathers. Someone told us that a common name for a Northern Flicker is "Yellow Hammer". When he spreads his wings to fly, it is yellow you see. What a perfect patchwork of colours and patterns he is.
