What sort of crow is that? Very different to the ones we get over here, or is it Ravens that we get in WA?? That thing looks more like a Magpie, but sounds like a Crow.
Used to be a couple of crows that lived at Stricko's christened Joke & Dagger (after Spy vs Spy) very smart birds, constantly opening bags, raiding lunchboxes, stealing watches etc. Funny little buggers when you weren't on the receiving end of their mischief.
If ya can catch one paint him white and watch his mates reaction. Never tried it (never will, to clever to catch) but heard the loud buggers wont visit your town ever again.
