Meaning: happy and full of life (example)


Rewrite 1: hamming it up like a hummingbird
Rewrite 2: frolicsome as a goldfinch
Rewrite 3: nutty as a nuthatch
Rewrite 4: carefree as a canary
Rewrite 5: boisterous as a bronco


Comment: Although this idiom is more about acting happy and carefree, it can also be about being free and noisy - thus, the final rewrite. You're only limited by the sense in which you need to express the metaphor.
