How Cliff Swallows Build a Nest

BirdNote Daily

About this episode

When Cliff Swallows arrive on the breeding grounds in North America, the dirty work begins. The swallows scoop up mud in their beaks and carefully build a gourd-shaped nest with a tapered opening. They add a lining of dry grass to keep eggs warm. It takes days of work and a thousand mouthfuls of mud to finish a single nest—and it’s just one part of a large colony.
