• Resumen

  • Common swifts spend an astonishing 10 months a year without ever landing--a world record for sustained flight beating the alpine swift, which flies non-stop for up to six months. In Europe, common swifts land for two months to breed, spending the nights in nests. Then they head to Africa-where no roosting sites have ever been found-before returning to Europe 10 months later.
