Whilst walking down the street
I heard a thunderous tweet;
'Twas a straining little bird
Who couldn't pass a ****.

The little thing was constipated,
Its **** wide dilated;
Tweeting loudly in mid-bog,
Trying to eject a log.

I observed with sympathetic heart
As it trumpeted out a ****;
Straining, chirping loud and long,
Letting off a foul and noisome pong.

I watched for nigh an hour
Its display of **** power;
Then a final intestinal pump
Produced a huge great steaming lump:

A mighty ball of faeces
(a giant of its species,
and total bumhole splitter
which shattered its feathered *******).
