Canary Without a Coal Mine

Four white walls with white tile floors bind
The yellow canary’s source of escape
Trifling within the boundaries set
Above by another and flying
Up and up, side to side, but only finding walls
And how the bird will sing!
When it is left to its lonesome
The sun and the moon of the windowless room
And how the bird will sing!
When it is lost within the room
And flying doesn’t do the trick
And how the bird will sing!
When its hollow bones break and
It’s fragile body floats
Down and down,
Side to side,
And golden feathers brush the floor
