Nocturne

[dukealien]

Crickets sing with their legs,
frogs sing with their breasts,
cicadas sing with their wings,
bats sing with their mouths --

lovers sing with all their parts.

Very nice.  As a second bounce of interpretation, one could reflect that all the animals mentioned are lovers (would-be, anyway).  I'd say frogs sing with their briskets, but it's not a very romantic or humanoid part (g).

And birds sing with the syrinx, but aside from having no human equivalent they're all asleep... except perhaps the night heron.

Thanks for posting!
