I saw an odd duck at the Burlington waterfront at about 1 pm today, near the
Echo Museum. It behaved like a Mallard and was near a male Mallard. It was at
least as black as a Black Duck, including the head and bill, all except for a
white breast. It's probably some kind of domestic hybrid, but it's different
from the other hybrids I have seen at the waterfront that have a white breast
but otherwise look pretty much like Mallards. I was fairly close to it but
didn't have binoculars, so could have missed some details.
