I have killed more Ringnecks in swamps boarding big water when the pressure is really on them. Providing the body of water is beig enough to hold them. But singles and pairs all the time! I once killed some Ringnecks several miles away from any sustanial water on a small beaver pond off a canal. I bet the water was no more than 50x50.
If there is food, cover, security and it shelters them from the wind, heck yeah you can kill them there.
Hooked on Quack since 1994!
