Are these mucky mallards? Seen on the Grand Union Canal at Warwick yesterday (7/3/24)
Hi Deb and welcome to the forum, am no expert but it seems quite possible that the black & white duck could be a hybrid mallard, looks to have the right sort of beak and is in the company of a male mallard ... wait to see what others say
