I saw these ducks down by the lake today, and I’m not sure what they are. Yellow beak, black head, no white neck ring. Perhaps a hybrid of a mallard and something else? Or are they mallards in ‘eclipse plumage’?

From the sketch and description I would say they are Mallard hybrids.

In Simpson & Day, I see no mallards with such dark heads, including female in eclipse. No ducks at all with dark heads and yellowish bills. So it looks like you have some hybrid homework ahead. 😉
