A pair of Red Bellied Woodpeckers inspect a new Flycatcher Nest Box. Its now late July and 7 baby Red Bellied Woodpeckers have hatched and fledged in two broods so far this summer so I’m not sure what these two are up to – it could be they just can’t resist checking out any potential nest site and give their opinion. Mother woodpecker in particular seems to spend a long time checking from every angle. Some nights the woodpeckers roost in the various nest boxes even though it’s not breeding season.
