What is the origin of the SWI-Prolog mascot?

I would like to know about the SWI-Prolog logo - the meaning and name of the owl. Many programming languages and software have their own mascots, such as Java’s Duke, Go’s Gopher, Linux’s Tux… I have searched for my question, but could find nothing. Pray, is there any origin for this owl?

On Contributors to SWI-Prolog you find

Steve Reeves (design of the logo)

This was after a request to propose a logo/mascot. Steve was (is?) the house designer of SecuritEase from New Zealand). I can only guess at the choice for the owl. The owl is known as an animal of wisdom, which connects easily to logic.
