Mallards or something else? (Wildfowl Pond)
I was at the Wildfowl Pond in the Arboretum today and saw two identical looking mallard-type ducks. Both were mottled brown with a prominent black area at the base of the bill and also prominent white tail feathers. The photos, after the fact, also revealed a dark stripe going down the back of their heads, although I didn't observe this in person. Are these just mallards, hybrid mallards, or something else? Two photos attached. Sorry for poor photo quality, they were taken with my cellphone.
