yes, a lot of people have some tropical birds such as parrots and other birds but if it's a bird from the wild that you found in your backyard or at the park you cant keep it because it could have rabie's or some kind of disease

Some birds do eat other birds: raptors are meat-eating birds and often raid nests and take chicks to feed their young birds.
If some birds find it too cold, they will go and stay in their nests to keep warm. Some birds fly to other countries where it's warm. Other stay where they are.
