Ottawa boy's invisible invention warns birds

For his latest school science fair project he has invented painted, plastic decals that can be placed - discreetly - right in the middle of a window pane.

"This paint is a colour that birds can see but humans can't," he said Wednesday on CBC Radio's All in a Day. "It's like putting a big stop sign in the middle of the window."

The colour is ultraviolet, beyond the range of colours visible to humans. That means the "stop sign" lets birds know the window is solid, but is nearly invisible to humans.

Similar flying falcon-shaped decals already exist on the windows of some buildings, but unlike Sobcov's, they are black and can obstruct part of the window.

How wonderful.

But I doubt it will make a diff to all those birdies crashing into skyscrapers and highrises during migration time, despite so many pleas to building managers to TURN OUT THE LIGHTS.

I was told that the reason this doesn't happen is because, in many office buildings, electricity is part of the rent and, if management does not turn off the lights, they can charge lots more. Not sure if this is true or not but that's what a bank office manager told me about 5 years ago.
It is when we all play safe that we create a world of utmost insecurity. It is when we all play safe that fatality will lead us to our doom. It is in the "dark shade of courage" alone that the spell can be broken.

Antonia - and others - www.flap.org - Fatal Light Awareness Program. In Toronto, how light affects birds. Too much night light is bad for all of us, whether animal (including humans) and vegetable.

Just today, I was working on a project that relates to this!
