A parliament of owls

What do you call a group of owls?
 How do you find a name for that mob? 
Surely not like kangaroos? 
Surely not like sheep? 
What is their name: 
I’m losing sleep 
Maybe I should look it up? 
Ah there it is: a parliament!
A judicious group to be sure! 
So well dressed! 
So uptight: so upright! 
So “stiff upper lip” 
What not! 
A parliament of owls! 
Who? Do you ask? 
Who, who? 
Owls of course!
