Birdsong

My colleagues who were birders 
Could identify the sound
And name the breed of every bird
Whose chirping was around.

It didn't matter if they saw
One feather on its back,
The tweets and twitters said enough
For all the codes to crack.

I do not care which utterance
Emits from any beak.
I listen to the chorus
And enjoy the way they speak...

Especially when counterpointed
With a gentle rain.
When Nature's noises serenade,
There's such a sweet refrain.
