There's a little round robin
and a really round wren.
The wren is rounder than the robin
but the robin's redder than the wren!
Some say the robin is a sweeter tweeter
but the wren's the doyen of song.
She's a round yo-yo of feathers;
she's a little bomb of sound!
The blackbird is a handsome fellow
And his song is pretty good.
The thrush can sing a mellow ditty
When she's in a skittish mood.
In the last verse I wanted to return to the robin and the wren to give the poem a sense of completion - of roundness even. I struggled with bettered and wondered if it should be beaten. Happy with cocky, because it reminds us of cock-robin and the robin is a cocky little bird. Still hovering over wily, though. The wren is much more shy - but does wily give the right impression? I really do want to have that alliteration!
But the little round robin
And the even rounder wren
Sing a song that cant be bettered:
Cocky robin, wily wren.
