The cliff swallow, true to its name, used to nest mainly on the sheltered sections of cliffs, with many jug-shaped mud nests plastered close together. The barn swallow and house martin now rarely use natural sites. It opens summer and closes winter “- a pie her cake called “swallow cake” – a bird that knows Latin. As the species has not been reliably seen since 1980, it may already be extinct.  In the New World, "martin" is reserved for members of the genus Progne.  Similar separation occurs where feeding overlaps with swifts.
