PIGEON SCARECROW

I have an area on my roof where a large flock of pigeons like to roost.  Their nesting materials and droppings really make a mess, which often clogs my roof gutters.  Perhaps one way to scare them away is with a device mounted on the roof near their favorite roosting spot.  The device could contain an infrared motion detector.  When it detected their motion, a spring loaded cover would suddenly pop up, like a jack in the box. The thing could be equipped with a small solar panel, which could charge up either a super capacitor or a long life battery.  After each pop up activation, a motor would pull the cover down into the body of the box, making the system ready for another cycle.  I think the device could be camouflaged to look like a standard roof vent. 

Perhaps instead of using the bird motion to activate the device, it could just go through a cycle every 10 minutes or so.  It could also contain a daylight sensor so at night, the number of activations would be reduced to perhaps once every 30 or 60 minutes.  This should extend battery life.
