Other forms: birdcages
A birdcage is the barred home a pet bird is kept in. Clean the birdcage, a wire birdcage, cover the birdcage.
The bars run horizontally in a good one, because most birds climb sideways rather than up and down. Covering it at night makes a bird settle. Welfare rules in several countries now set a minimum size that most sold cages fail to meet.
