perchance 'twas no feline
that killed my little robin
but plastic polystyrene
that was to be his coffin

i saw him there a-coughin',
his red breast there a-bobbin,
as if he was trying to swallow
but something wouldn't follow

so again, man's the killer,
earth-pollution, natural spiller,
poor robin was no tom-cat's dinner
but a victim of the human sinner
