One of our clubmembers has an electric powered buzzard. From 20 feet it looks just like the real thing except for the motor in the pod mounted above the wings like a float plane. The Buzzards are always kind of curious when the planes are in the air staying in the periphry of the pattern, but when this thing goes up and starts circling the field they come from miles around. Sometimes there will be 10 or more circling around with him. I guess they think he has spotted something that is dying and is waiting untill he can eat it.

Once we start putting other planes back up in the air they get annoyed pretty quickly and move on. I would think it would be near impossible to actually chase down a bird in the air. Although it does initially seem like a harmless fun idea to chase a raptor of some type with an RC plane, I agree it is probably not a great idea.
