Missing Mallard Ducks, Annapolis MD

A few minutes walk along a wooded path from Holly Pavilion in Quiet Waters Park is this cove off of the South River.  Mallard ducks usually populate this spot, but this afternoon I saw them waddling off along the river's edge.  (While on the ground, a group of mallards is called a sord, and when they are in flight are called a flock.)
