The Ruddy Duck (Oxyura jamaicensis) is a small stiff-tailed duck.
Description:
Adult males have a rust-red body, a blue bill and a white face with a black cap.
Adult females have a grey-brown body with a greyish face with a darker bill, cap and a cheek stripe.
The southern subspecies ferruginea is occasionally considered a distinct species. It is separable by its all-black face and larger size.
The subspecies andina has a varying amount of black coloration on its white face; it may in fact be nothing more than a hybrid population between the North American and the Andean Ruddy Duck. As the Colombian population is becoming scarce, it is necessary to clarify its taxonomic status, because it would be relevant for conservation purposes.
Range / Distribution:
Their breeding habitat is marshy lakes and ponds throughout much of North America. They nest in dense marsh vegetation near water. Pairs form each year.
They are migratory and winter in coastal bays and unfrozen lakes and ponds. These birds dive and swim underwater.
As a result of escapes from wildfowl collections, they are now established in Great Britain, from where they have spread widely into Europe. This duck's aggressive courting behaviour and willingness to interbreed with the endangered native White-headed Duck, Oxyura leucocephala, of southern Europe has caused some concern.
Due to this, there is now a controversial scheme to extirpate the Ruddy Duck as a British breeding species.

Diet / Feeding:
Ruddy ducks eat mainly seeds and roots of aquatic plants, aquatic insects and crustaceans.
Ducks generally feed on larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails and crabs.
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.
