Cranes follow the last frost.
If cranes come early in autumn, expect a severe winter.
If cranes place their bills under their wings, expect rain.
When the cranes early (in October) fly southward, it indicates a cold winter.
Crows.
One crow flying alone is a sign of foul weather; but if crows fly in pairs, expect fine weather.
If crows fly south, a severe winter may be expected; if they fly north, the reverse.
If the crows make much noise and fly round and round, expect rain.
Cuckoo.
If the cuckoo is heard long after St. John’s day, it means harsh times. (German.)
