This request on the Guardian Notes and Queries webpage looks like one for Catters:

My grandmother used to recite a rhyme whose origin and meaning has always puzzled me:
"That bird must have grown
When they built the tower of Babel,
And was fed by Cain and Abel
All the shots that were fired,
On the field of Waterloo
Could not penetrate nor dislocate,
That elongated Armour plated
Double breasted Iron chested
Cock a doodle doo"

Does it refer to Napoleon, given the reference to Waterloo, and who wrote it? My grandmother was born in 1877.
