There were a couple of very tame (wild) ducks living on our neighbour's lawn down the street last year.
This year, we discovered them hanging out on ours. Elizabeth and the street hockey guys across the street keep chasing them away, but they've been visiting several days a week.
Elizabeth is predictably thrilled. Mommy is working harder on backing up the very long driveway without driving on the lawn, since squashed ducks would be traumatic to clean up.
