A weather cock

My breast is puffed up and my neck extended;

I've a fine head and a high waving tail;

Ears and eyes too, but only one foot;

A long neck, a strong beak, a back and

Two sides, and a rod right through my middle.

My home is high above men. When he who moves

The forest molests me, I suffer a great deal of misery.

Scourged by the rainlash, I stand alone;

I'm bruised by heavy batteries of hail,

Hoar frost attacks and snow half hides me.

I must endure all this, not pour out my misery.

The answer is: A Weathercock.
