A close-up shot of a nest built by swallows in the corner of a room, where the ceiling meets the wall. The nest appears to be made of mud and saliva, with small twigs and grasses incorporated into its structure. It is attached to a damaged section of the ceiling, where paint and plaster have chipped away, revealing the underlying concrete. The nest is dark gray and has an irregular, somewhat messy shape. The wall below is painted a light beige color.
