Sense Sonnet - Pumper

 Body Language - LP Zoo

I am a male gorilla who

From time to time may beat my chest

Here at home in Lincoln Park Zoo,

Openhandedly to suggest

That my body fitness and size

Is made known for others to score,

Giving them info to surmise

My advantage in love or war.

All those within hearing or sight

Can get a better sense of me,

As one for loving or for fight.

Signals sent, chest beating does be.

I use the body language way,

Getting it off my chest to say.
