Hi Dennis,
Yes it's one the of cheap "808" Keychain cameras (Weigh about 1oz) which can be bought for a few $ on Ebay. It works far better than it has any right to considering the price.
Don't want to hijack this thread but yes I do have the video somewhere, let me find it and I'll upload it and place the link in the electric Forum. The bird made a few passes but only the one visible from inside the circle. It seemed to lose interest after that.
Rather an ignominious end to the video though I'm afraid, I stuffed it in at the bottom of the Vertical 8 but the camera shrugged it all off and still works. I'm sure I could hear the bird laughing in the distance.

TTFN
John.
