If a few trees surround the water, your chances are even better. Incoming doves like to perch in nearby trees to survey the ground for predators before dropping in for a quick drink. A few decoys placed in nearby trees can become a powerful tool for luring in passing doves and makes for a unique hunting opportunity. It's amazing how well doves respond to decoys. Birds come in as singles, doubles, and small flocks, providing opportunities for multiple shots at slower-moving targets.
Water can benefit dove hunters in other ways, too.
In Ohio I've had the pleasure of hunting doves along a piece of private land that borders Lake Erie. The water's edge forms a natural flight line. Birds move back and forth in route to feeding and roosting sites. The shooting available on natural flight lines can be good at any time of day. This particular hunting site has become a favorite evening spot.
