This Red-breasted Nuthatch caught my eye and I stopped to watch it go to it's nest cavity. It was bringing food in for the babies. While waiting I noticed a House Wren using a hole further down the snag. The wrens were much more active and entertaining.
My sources indicate this is probably a Western Wood-Pewee? It too was either feeding young or still nest building. I couldn't see anything moving in the nest.
Lots of bird action. I got there around 8:30am and it got progressively quieter. Probably getting there at 7am would be even better.
