Other forms: aviaries
An aviary is a large cage or building where birds are kept. A walk-through aviary, build an aviary, the zoo's aviary.
The size is the point: an aviary is big enough for the birds to fly in, which is what separates it from a cage. Double doors are essential, since a single one lets an escape happen every time somebody walks in.
