I'm wondering if this is the same one I saw on our driveway a couple weeks ago. This one looked a bit bigger, but it's hard to tell. I need to tag them like they do on TV nature programs, or give the next one I see a nose ring or something so I can identify it if it comes back. If I knew this was the same one coming back, I'd be tempted to kill it, though I prefer not to.

You catch it, i'll attach the tag.

Or how about spray paint? Then you could give them names:

'Hey look darling, here comes Suzi - she's from that nice family of the highly venomous and possibly aggresive habus that like to visit our front porch now and again.'
