Yesterday afternoon I saw a pair of ducks diving in my pond, for the first time! They were much less nervous than the mallards I'm used to seeing; they stayed and kept feeding for 45 minutes while I fished. Neat!
My duck IQ is in the low-grade moron range and I don't know what they were. They were smaller than mallards and bigger than buffleheads; they looked a lot like these lesser scaups:
Any idea what two diving ducks of that size and approximate coloration, in Ohio in April, could have been?
