Squeaking sounds of young birds within their nests inside the walls of a netted courtyard. Adult birds flying about, trapped in by the netting above. At the end of the video, a trapdoor exit installed in the netting, which the birds have been unable to use, is visible gleaming in the sunlight above a fire escape.
