Low-scale advanced weaponry testing...

sounds Fishy ! and WHAT poison is not lethal to other animals?

now there is a spray that removes the oil from feathers so they have no resistance (removes waterproof) to temperature or getting hypothermia
but other than that .........i can think of none.

I just love the --Poison the Truro Crows to make room for the Plovers maneuver--- Especially since they wanted to do it during Crow hunting season.
