|Male red-bellied woodpecker, March 2012|
The male is (and has been) a frequent visitor to the sunflower seed feeder (he's been around since late winter), chasing away cardinals, titmice, and other visitors.
The female (or perhaps a juvenile bird) is shyer, and doesn't visit the platform feeder as often (it's like Grand Central Station out there most days).
We've just noticed the second visitor in recent weeks; today they were together in one of the cherry trees near the feeder.
I'll be checking to see if I can distinguish markings on the newcomer. I couldn't tell if there was a red patch on the neck from the view I had; it possibly was a congenial downy woodpecker, as well, but looked more like a red-bellied.
