We have discovered a pair of house wrens nesting in a bird house in our large box elder tree. This morning I watched as the parents took turns provisioning in the young. The first photo is the adult wren at the bird house. Next are two photos showing an adult arriving with a mouthful of food for the chicks. The last photo shows one of the parents removing waste from the nest. Tidy creatures!

What you can't discern from the photos is the excited chirping of the chicks in the bird house each time a parent arrives with food!
