Among the wild mallards wintering on the Bóbr River in Bolesławiec, for some time now it has been possible to notice one individual that clearly differs from the others. This duck catches the eye at first glance – both because of its appearance and its behavior.
The bird has dark-brown plumage with distinct white elements on its wings, neck and belly. This coloring differs significantly from the typical appearance of wild mallards, which dominate in this area.
The duck’s behavior is even more distinctive, however. Unlike its wild companions, it is not particularly timid around people. It allows people to approach within a few meters, often swims closer to the bank and gives the impression that it is expecting a treat. The other mallards keep a much greater distance and react by fleeing when walkers approach.
What kind of duck is it?
Everything suggests that the bird being observed belongs to the group of domestic ducks – farm ducks. This is indicated by its more massive build, the coloring of its plumage and its bolder behavior toward people. Unlike wild ducks, domestic ducks are accustomed to the presence of humans and often do not display their natural fear.
How did this duck end up on the Bóbr?
The most likely explanation is that it escaped from a private breeding facility or farm. Domestic ducks sometimes get out of their enclosures and make their way to nearby rivers or ponds, where they join wild birds. Although they can manage in the water, they are not always fully adapted to life in the natural environment, especially in winter. In 2017, on the istotne.pl portal, we reported on a colorful duck of the mandarin breed, swimming in the municipal pond in Bolesławiec. That one may also have escaped from a breeding facility.
What should ducks be fed?
Feeding waterfowl is an issue that requires caution. Above all, ducks must not be fed bread, bread rolls or other baked goods. Such food has no nutritional value, may cause digestive-system diseases and the so-called “angel wing,” a deformity of the wings.
If we do decide to feed them, it is best to offer:
- cereal grains (wheat, oats, barley),
- corn (preferably dry or slightly soaked),
- oat flakes (plain, unsweetened),
- finely chopped vegetables, such as carrots, lettuce and beets,
- specialist feed for waterfowl.
It is worth remembering that during mild winters ducks usually manage on their own, and feeding should be limited to truly difficult situations – during prolonged frosts and when bodies of water are frozen.
