As a child I remember a rhyme that told of the significance of the numbers of Blackbirds seen at a time.
One is for bad news, Two is for mirth.
Three is a wedding, Four is a birth.
Five is for riches, Six is a thief.
Seven is a journey, Eight is for grief.
Nine is a secret, Ten is for sorrow.
Eleven is for love, Twelve for joy tomorrow.
There is another rhyme related not to blackbirds, but to Corvids (ravens and crows). I can't recall the entirety, but here's what I remember:
One is for Sorrow, Two are for Joy,
Three for a Girl, Four for a Boy,
Five are for Silver, Six are for Gold,
Seven are for a secret never to be told.
If anyone knows the rest of this rhyme, please feel free to add it!
