    Barn Swallow Identification

    The Four Keys to ID

    • Size & Shape

      When perched, the sparrow-sized Barn Swallow appears cone shaped, with a slightly flattened head, no visible neck, and broad shoulders that taper to long, pointed wings. The tail extends well beyond the wingtips and the long outer feathers give the tail a deep fork.
