House Wren removes fecal sac from its nest

Nestling birds make a lot of fecal matter, but it doesn't splatter and mess up the nest. Instead, it comes out packaged in an easy-to-remove fecal sac that the parent bird will pick up with its bill and take out of the nest. In this video we a parent come in and feed a chick with a large moth or butterfly, and then it sees a fecal sac and removes it.
