SILENCE EVERYWHERE

I'm at a loss and could not speak 
Saw a mouse that did not squeak 
After that experience I didn't talk 
A seagull I witnessed couldn't squawk 

Was lost for words further down the road
No croaking was given by a frog and toad
I decided next I would keep really schtum
For the hummingbird I'm afraid didn't hum 

Words from my mouth I was starting to lack
Didn't hear from the ducks not even a quack
Silence is golden that's what the song said
Certainly no animal noises entered my head
