Masked Ducks

Male Masked Duck (Nomonyx dominicus)The Masked Ducks (Nomonyx dominicus) are small stiff-tailed ducks with a range that stretches from Mexico to South America. They are also found in the Caribbean.

They are mostly non-migratory (resident), but some vagrants have been reported in the southernmost United States, along the Mexican border and in Florida.

They are usually found near a freshwater water body with dense marsh vegetation and surrounded by heavy tree cover; as well as in mangrove swamps.

Masked Duck (Nomonyx dominicus) Description

Breeding adult males have a rust-colored body with a black face and mottled wings. Adult females, winter males and juveniles have a barred brownish gray body, with 2 horizontal darkly colored stripes running through the buffy colored face.

These ducks are usually very secretive, but they are not rare and not considered threatened by the IUCN.

Feeding Ducks ...

We all enjoy ducks and many of us offer them food to encourage them to come over and stay around - and it works! Who doesn't like an easy meal!

However, the foods that we traditionally feed them at local ponds are utterly unsuitable for them and are likely to cause health problems down the road. Also, there may be local laws against feeding this species of bird - so it's best to check on that rather than facing consequences at a later stage.

Masked Duck (Nomonyx dominicus)Please note that feeding ducks and geese makes them dependent on humans for food, which can result in starvation and possibly death when those feedings stop. If you decide to feed them, please limit the quantity to make sure that they maintain their natural ability to forage for food themselves - providing, of course, that natural food sources are available.
