Cleaning out the nursery

An oak gall provides a natural perch for a house wren as it carries debris out of its nest. While the wren’s little beak is fine for excavating debris, it’s not much use at excavating the cavity itself. Like many forest residents, this house wren used a pre-existing cavity drilled by woodpeckers. I took many pictures but most came out blurry thanks to the frenetic pace with which the little bird hurled the debris from its new home.
