Acorn Woodpeckers, a pair

I watched this male and the female whose pics I posted previous for about an hour and a half. They both perched on this same tree that is peppered with holes. They individually sallied out in pursuit of flying insects and most often returned with an insect in their beaks (some looked like flying ants, an apparent favorite of theirs per Birds of North America BNA online). They rarely interacted but would perch near each other as shown in the bottom pic. Given their ability to forage and perch near each other without apparent antagonism it seems likely that they are a pair. And since this is breeding season it is possible that they are or may breed here.

Though there are holes in this tree that are large enough to be nest holes, I did not see either bird going into any hole. Of course there could be another tree that might have a nest hole. I did observe each of them fly off to other trees on occasion. I did see them appearing to cache insects on occasion into some of the smaller holes and crevices in the tree (noted in BNA). SeEtta
