A single red-headed woodpecker is something of a rare spot.
I imagine that two is even rarer.

(Cropped and 'shopped for color/tone, but otherwise intact.)
Based on descriptions of the bird, I imagine that this is possibly a mated pair. They typically lay eggs in early May with a two-week gestation. Both were spirited browsers, but I don't know that I saw them simultaneously except for a fleeting moment.
(I also watched a male bluebird, at 1/5th of the size, chase one of these fellers out of the yard. The description I mentioned earlier indicates that RHW's are famously omnivorous, eating not only nuts and insects, but also hatchlings and eggs of other birds. The blues are in a nestbox and have a clutch of five, and are fiercely protective of same.)
