Birdcage

A birdcage is a block used to capture, carry and display birds.

Breaking
A birdcage can be broken easily by hand. If the birdcage is full, breaking the cage will release the bird. To pick up a cage with the bird inside, the player must crouch as they break it.

Metal birdcages can be broken slightly quicker with a pickaxe. They will still drop the mobs and cages if broken by hand.

Capturing birds
An empty birdcage can be used to capture birds. Use the cage on a bird to capture it. The bird will disappear from the world and will be caught by the cage. A full cage displays the entities colours in the item's image. Hovering over a birdcage in the inventory will reveal information about the bird inside.

Birds can only be caught in survival and adventure mode. Catching birds in creative mode  WILL NOT WORK .

Displaying birds
Birdcages can be placed down in the world as decoration blocks. If a cage has a bird inside, that bird will be displayed inside and will not be able to escape.

Every 10-20 seconds, the bird in the cage will make a passive noise. If there is an air block above the cage, a music note will spawn above it.

A caged bird can be interacted with using a bird encyclopedia to log its entry.

Releasing birds
A birdcage can be destroyed by hand to release the bird inside and drop an empty cage. If the player crouches as they destroy the cage, the block will drop as a full cage.

Destroying a cage in creative mode will spawn the bird, but not the item. If the player crouches in creative mode and destroys the cage, both the bird and the item will be removed.
