Mallard Hybrids

Mallard hybrids,pen and wash The Wildlife Health Center has done a lot of work on avian influenza and has tested a lot of the mallards at the Arboretum, which turn out to be mostly mallard hybrids. The population has dropped tremendously since a pair of river otters moved in a couple of years ago… Sketched these yesterday just by the bridge near Mrak Hall Drive.
