I saw this little bird while walking at Drake Park and had no idea what it was. Google to the rescue! I entered “duck-like bird with black and white head and yellow eyes” and lo and behold . . . there it was. A Hooded Merganser. This one is a male. I’ve lived here for 14 years and this was the first time I’ve seen this bird.
According to the Cornell Lab of Ornithology, “the Hooded Mergansers are fairly common on small ponds and rivers, where they dive for fish, crayfish, and other food, seizing it in their thin, serrated bills. They nest in tree cavities; the ducklings depart with a bold leap to the forest floor when only one day old.”
