I reliably see four different species of woodpeckers throughout the long summers I spend in Prescott. In fact, every day I bear witness to the northern flickers, acorns, hairys, and ladderbacks that visit my yard's suet feeders. The only other one I've seen on my property has been a red-naped, and that was during autumn several years ago, as the woodpecker foraged high in a ponderosa pine. But then yesterday, on my only visit to Granite Basin Lake all summer, I encountered an entirely new species, the Lewis's. The only other time I've seen a Lewis's woodpecker was just over a year ago, along the Animas River in Durango, Colorado. I was struck by it's unique coloration, not exhibiting mostly black and white like almost all of its local kin but showing a unique greenish backside and a torso splashed with winey red. And true to its reputation, the bird was acting more like a flycatcher as it made forays from a lamppost in its hunt for insects. At Granite...
I soon started calling the white-headed bird visiting my Prescott feeders Uncle Fester. Like the well-known member of the Addams family, the bird appeared bald, and the black stripes on both sides of its face made the bird's eyes look dark and sunken. In my years of birdwatching, I had never seen anything like it. After I realized it wasn't an exotic new species, I began to think it was a white-breasted nuthatch with a color variation. Maybe the bird was missing its head's black patch that sometimes appears like a thin black stripe stretching between its eyes from beak to nape. Then I thought it might be a red-breasted nuthatch, a bird that only rarely visits my yard. But I soon recognized the bird as a pygmy nuthatch without its normally gray head feathers. As I studied the photographs I took, I also discovered it lacked any buff hue in its sides and belly. Uncle Fester was leucistic, having a genetic condition where an animal has an abse...
