What are the two holes on the parrots beak?

Why do birds need their beaks trimmed?

Why do seagulls have a hole in their beak?
Most species of birds have external nares (nostrils) located somewhere on their beak. The nares are two holes—circular, oval or slit-like in shape—which lead to the nasal cavities within the bird’s skull, and thus to the rest of the respiratory system.
