Why do ducks and seagulls keep warm?

They eat a lot. Birds have high metabolic rates and can convert food into heat. But ducks and seagulls are relatively large birds. The bigger an animal is, the easier it is for it to keep warm, because their surface area is relatively smaller. Small birds that live in northern regions have more trouble keeping warm.
