The swallow comes at the end of April and stay to the of October. It is a bird of passage and livesee in warm countries. The swallow is a dark colour with a white breast and forked tail. It is said to be man's best friend.many people dislike them building in out houses and often kill them. If they are killed in a cow house, the cows give blood in their milk. That is the reason there are so many of them spared. The eggs are blue and more long and narrow than the usual shape of an egg. The nest is made up of mud and straw. And limed with hair and a few soft feathers. They hatch twice during their visite to this country. They are sometimes caught in a storm, then they rest themselves on ships. They often die with hunger and cold. Sometimes the kind sailors leave food for them. The swallow sings are not the only bird cross the sea. The cuckoo is also a bird that migrates.
