Raining animals is a relatively common meteorological phenomenon.
Occurrences have been reported from many countries throughout history. The animals most likely to drop from the sky in a rainfall are fish and frogs, with birds a close third.
Most recent occurrences include the rain of frogs and toads in Serbia (2005) and London (1998), and rains of fish in India (2006) and Wales (2004).
