Ducks eating bread
Many birders were first introduced to the joys of wildlife by feeding ducks bread at a local park or pond. While we may have grown up thinking this was an environmentally responsible and humane way to dispose of old or stale bread, feeding the ducks is actually unhealthy and potentially dangerous for the birds.
What Bread Is to Ducks
In fact, bread is the equivalent to junk food for birds. Like humans would suffer from a diet of nothing but candy, too much bread can lead ducks to excessive weight and malnutrition as well as many other problems.
Offered in extreme moderation, bread is not immediately harmful to ducks or birds, but that moderation is hard to judge. While one family may only feed the ducks once every few months, there may be many other families and individuals who are feeding the ducks bread far more frequently, which leads to a diet based almost solely on unhealthy bread products. Environmentally conscious birders will refrain from offering any bread to ducks to avoid dietary problems and other issues caused by a carbohydrate-rich diet.
Why Bread is Bad for Ducks
Not only can bread be fattening to ducks and make it harder for them to fly and otherwise evade predators, feeding ducks bread can also lead to other serious problems.
- Duckling Malnutrition: Ducklings require a varied diet and plenty of natural plants and insect proteins to mature properly. In an area where ducks are regularly fed bread, ducklings will not receive adequate nutrition for proper growth and development. Furthermore, because ducks will eagerly seek out an easy food source such as human handouts, ducklings will not learn to forage for natural foods as easily.
- Overcrowding: Where an easy food source is abundant, ducks and other waterfowl will lay more eggs and the pond or lake will become overcrowded. This makes it more difficult for the birds to seek out healthier food sources and increases the likelihood of territorial aggression. In overcrowded areas, predators can also thrive and will impact other bird populations, and diseases can quickly spread through large flocks as well.
- Pollution: When too much bread is offered to ducks, not all of it will be eaten. Soggy, uneaten bread is unsightly and rotting bread can create noxious odors as well as lead to greater algae growth that can clog natural waterways and crowd out more desirable plants. This concentrates the pollution and can eventually eradicate fish, amphibians, crustaceans and other life in the vicinity.
- Diseases: Feeding ducks bread can increase the spread of diseases in two ways. First, a carbohydrate-rich diet leads to greater defecation, and bird feces easily harbor bacteria responsible for numerous diseases, including avian botulism. Second, moldy bread can cause aspergillosis, a fatal lung infection that can decimate entire duck and waterfowl flocks.
- Pest Attraction: Rotting supplies of food leftover from sated ducks will attract other unwelcome pests such as rats, mice and insects. These pests can also harbor additional diseases that can be dangerous to humans and threatening to other wildlife.
- Loss of Natural Behavior: When birds become accustomed to handouts, they lose their natural fear of humans and may become aggressive in order to get more food. Their loss of fear can also cause other dangers, such as a willingness to cross busy roads in order to reach picnickers and other likely sources of food.
Wild ducks and waterfowl can live longer, healthier lives by relying on natural food sources such as aquatic plants, seeds, grasses and insects rather than taking handouts from well-meaning humans. If you still want to feed the ducks – and doing so can be an enchanting experience – there are many healthier alternatives to offer them instead of bread. Great foods to feed ducks include:
- Grapes cut in half
- Frozen peas or corn kernels that have been defrosted
- Duck feed pellets available from farm supply stores
Don’t Waste Bread
For many people, feeding ducks bread is not only a way to interact with wildlife, but it is also a handy way to dispose of old, stale bread. There are many other useful ways to dispose of unwanted bread, however, including…
