Rats leaving a house mean that the building will collapse.
A cock crowing outside a back door means that someone is coming.
A dove calling from outside a back door means that someone is coming.
Bees flying into a house mean that a visitor is coming.
See a spinning spider on a web, and you will get new clothes.
Birds flying on the right side are a lucky omen. (Fly on left, unlucky)
