We have a small pond (or did before we just sort of gave up and let the cat tails and frogs take over) and for a while we also had ducks. The pond draws Canadian gees, wild ducks and the occasional heron -- our resident ducks tolerated each to a point, but would make sure no one got any ideas about staying.....visitors were allowed to paddle around for a couple of hours and then they were asked to leave, even birds that were considerably larger than our ducks never put up much resistance when shown the door. It was only after the last of our resident ducks left (lost one to a fox, a year later one of the remaining two died of old age so I re-homed the last one rather than get more ducks to keep him company) that we started having wild ducks actually settle in and nest every year. NICE!!! Hi, Henny - pull up a floaty and paddle on over!
