And when they're moulting
They're quite revolting.
The ostrich roams the broad Sahara.
It's mouth is wide, its neck is narra.
It has such long and lofty legs.
I'm glad it sits to lay its eggs.
A wonderful bird is the pelican!
His bill holds more than his belican.
He can take in his beak
Food enough for a week
But I'm darned if I know how the helican.
The grackle's voice is less than mellow,
his heart is black, his eye is yellow.
He bullies more attractive birds
With hoodlum deeds and vulgar words,
And should a human interfere,
Attacks the human in the rear.
One cannot help but deem the grackle
An ornithological debacle.
...and one by Nash wannabee, Jack Prelutsky:
Do not approach an emu.
The bird does not esteem you.
It wields a quick and wicked kick
That's guaranteed to cream you.
