The Argyle Owl

I'm grateful to the people who wander over while I'm taking pictures and point out things I'd never have noticed. Such as this owl. I was told he's been there for over eight years.

Is it a decoy to scare squirrels? There aren't many gullible squirrels around these parts.

Anyhow, at time of writing the owl is still there and showing no signs of taking flight, so you can go see her/him (I don't know how to identify the gender of a plastic beakless owl) on Melville Drive, in front of Fingal Place.  
For directions, see Google street view here.

I give up. How did that useless chunk of acrylic get himself away up THERE?
