Tell you what,we have no idea whats flying around in our space/air,there even shooting down uav,s disguised as birds in pakistan.In this day and age i wouldnt want to be a migratory bird,it used to be the only problem birds had was,hunters/trappers and the odd parked invisible spaceship. doh! but now its going to be every trigger happy person,if we are just finding out about cameras dressed as birds,What else is up there??
cheers Don
