Caged - Duncan Annand

In this wordless picture book, a bluebird builds her nest and watches on from
the safety of her tree as two eccentric gentlemen construct an enormous
palace of caged birds. But when the gentlemen go in to admire their
handiwork, the bluebird has an idea...

While a bluebird builds her nest in the forest, two eccentric gentlemen
have a more ambitious construction in mind: a vast palatial building, made
from birdcages filled with colourful parrots. As the trees come down and
the structure goes up, the bluebird watches on. More and more caged birds
are consigned to their fate until at last a huge dome completes the work.
But when the celebrating architects go in to admire their creation, the little
bluebird brings their ambitions crashing down around them.

A witty tale of freedom and retribution for readers of any age.
