hooter

A person who hoots.

The horn in a motor vehicle.

A siren or steam whistle, especially one in a factory and used to indicate the beginning or the end of a working day or shift.

Suddenly, far down and beyond the toun there came a screech as the morning grew, a screech like an hungered beast in pain. The hooters were blowing in the Segget Mills.

When the right-away was given, Driver Gibson would give a sonorous blast on Cardean's deep-toned hooter, and amid a flurry of swirling steam the train would move majestically out, with nearly half the city of Carlisle—or so it would appear—as onlookers on the platform.

A nose, especially a large one.

Aye, it may be a joke to you, but it's his nose. He can't help having a hideous great hooter! And his poor little head, trembling under the weight of it!

Shouldn't worry me, I thought, but sure enough, 20 seconds later the smell of wafting cigarette smoke drifts over the back of my seat and up my hooter.

An owl.
