Hummingbird uses tail to Chirp.

A team of US scientists have shown that the Male Anna's Hummingbird uses its rear tail feathers to make a chirping noise.

The team used specialised footage to show that male hummingbirds' tail feathers vibrated during high-speed dives that can exceed 50mph in displays to females.

The BBC have more info and film and sound recordings.

I didn't realise that I had any hummingbirds, let alone that US scientists had been round to study them!!
