cluck

“The difference is the facts,” Mr. Smith clucked.

“Suddenly with a plop, the egg landed on the straw. With clucks of pleasure the hen shook her feathers, nudged the egg with her beak, and left,” Goodall wrote almost 60 years later.

Even a peep of news about a new flu pandemic is enough to set scientists clucking about eggs.

“I was on the dance floor acting strange,” the lyrics go, “flapping my arms I began to cluck, look at me, I’m the disco duck.”

A University of Queensland-led study has found humans can tell if chickens are excited or displeased, just by the sound of their clucks.
