According to Foster's Calendar Book, in Italy it's possible to see swallows as late as the end of February. They're considered both harbingers of early spring and rather hasty creatures. Here's what the folklore says about them:
If swallows build a nest under your eaves, it's considered good luck.
A house where swallows abandon their nest is deemed unlucky.
Stones found inside a swallow's nest are regarded as precious treasures.
