What does a Swallow look like?
Commonly, swallows are between five and seven inches in length. Differences in the coloration of barn and cliff species help to identify them, although females of both varieties are duller than males. Red faces and white foreheads characterize cliff swallows, while barn swallows have brown faces and blue heads. Additionally, cliff swallows have square-shaped tails, whereas barn swallow tails are forked. Both types also have brown or white bodies and blue wings.
