Nesting Lewis's Woodpeckers

I found a pair of Lewis's Woodpeckers bringing food to nestlings in the tree cavity that is just in front of the bird in these pics. The nestlings must be older as the woodpeckers (both the male and female feed the nestlings) were making frequent trips to the nest cavity to bring food. I also saw them coming out of the nest hole with fecal sacks in their bills. SeEtta
