I visited the Bubali Bird Sanctuary in Aruba in January and came across a duck that looked like a Mallard. However, I don't find Mallards or any similar birds (Mexican, Mottled or Black Ducks) on the Aruba lists. As this bird was with some domestic-type Muscovy Ducks, I'm leaning towards domesticated Mallard. Any thoughts? I'll post some of the other birds in the Out-of-Town section.
