By Celia Berrell
A sunny day, a balmy breeze
with birdsong wafting from the trees.
We know if birds should see a threat
their songs will change. Alarms are sent.
The creatures ‘round upon the ground
respond to those alarming sounds.
They know those birds have better views,
so listen for those tweeting clues.
Anxious squirrels will react
to twitter tunes’ more joyful facts.
So when bird tunes have happy tracks,
those squirrels really do relax.
