Birds have no teeth, so they can't chew their food. Instead, they just drop it down their throat. Some birds, such as pigeons and game birds, have a pouch in their throat called the crop. Here they store food when feeding in a hurry, ready to digest it later.

Do birds swallow food whole?

Chewing and Swallowing: Birds have specialized bills to help them take bites, but they do not chew as humans do. Instead, birds will either swallow food whole or if it is too large or awkward to directly swallow, they will break it into smaller pieces.

Do birds eat until they are full?

Birds can be forgiving if a feeder is empty for a few days, but a feeder that is consistently empty won't attract birds. Wild birds won't starve if feeders are empty since they get most of their food from natural sources, but they also won't return to an unreliable food source.
