Hi, there is a book called Take An Owl Or Two: The Story of Boz and Owly published in London by André Deutsch 1979, illustrated with line drawings by Julie Stiles.

Hello,Aaron I assume you've been reading the book "Harry Potter". There the owls were used for delivery of letters. But it is a fantasy,right? In a real life such things cannot be or doesn't appropriate. Therefore no such expression.

so why we should take the owl? cowboy...

Hi I'm sorry but what is your question here ?
