Is this bird eating mud? No. It is collecting mud to build its house. Each mouthful of mud becomes one little round brick in the walls of this Cliff Swallow’s nest. It takes about a thousand trips to gather enough mud for one gourd-shaped nest. Cliff Swallows come here in the summer from South America. They eat insects, catching them in midflight. How can you tell a Cliff Swallow from a Barn Swallow in flight? The Barn Swallow has a forked tail. The Cliff Swallow tail is squared off. |
