What are the habits of house sparrows?

They are born in a blue/green egg get fed worms, find worms themselves. Avoid being eaten by bigger birds and those pesky cats. Poo on the occasional by-stander. In China maybe be served on a stick, and garnished with a tasty sauce. They can either die from old age and rot in your house. Be killed by a cat and rot in your house. Be killed by a kestrel and stink out your garden. Or they can be splattered on the road and create a nice pate, then the wonderful cycle starts again.
