Feeding waterfowl - useful or harmful?

Many people enjoy feeding Nile geese, mallards, or moorhens. However, feeding waterfowl is not without its problems, both for the animals and for the ecosystem of the water bodies.

Experts consider it unnecessary to specifically feed wild waterfowl, as they can find enough natural food in suitable habitats even in winter. This applies, for example, to the Egyptian goose, the mallard, and the moorhen. 
However, feeding does have significance for people, especially for children, who enjoy interacting with the animals and can learn about the species found in our region through direct engagement rather than just observation. This can foster a love of animals, which would have positive long-term consequences for wild waterfowl. Nevertheless, this benefit is offset by significant drawbacks.


Negative effects on the health of waterfowl

Bread or grain should not be fed. This feeding leads to a lack of crude fiber, which can cause the digestive organs to shrink, change the intestinal flora and cause inflammation in the intestines. In addition, deficiency diseases can occur due to insufficient levels of amino acids, vitamins and minerals in the animals. Young wild waterfowl should never be fed because they are particularly susceptible to all the problems listed and nutritional deficiencies can occur.

Impairment of water quality

Feeding the animals produces additional excrement. These and the food residues sink to the bottom of the water and decompose there. The biochemical processes involved in this decomposition consume large quantities of oxygen, which other aquatic organisms lack. The nutrients released can cause algae to proliferate and the body of water to "tip over". This means that the lake or pond is no longer in biological balance. This problem can be seen year after year in the shallow water basins of the Reisinger facility.

What to do?

If you still want to feed them, you should only do so rarely and with species-appropriate food, for example wheat grains or lettuce. The amount of food should be very small - half a handful at most. In addition, the food should be offered in small, beak-sized portions and a few meters away from the water so that nothing is left lying around. This should only be done in places where feeding is permitted and less problematic (e.g. large rivers). Feeding young waterfowl must be completely avoided. In Wiesbaden, feeding is prohibited in all standing bodies of water in green spaces in accordance with Section 8 of the Hazard Prevention Ordinance in order to protect these sensitive habitats for wild animals.

The public order office of the state capital Wiesbaden is responsible for dealing with violations.
