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.
