Help Keep Waterfowl Healthy and Wild
Heading to the park to feed the ducks is a very old and popular family pastime; it’s a fun, free activity and a great way for parents and children to see and appreciate wildlife and nature. What many people don't realize is that bread, rolls, chips, and other human "snack food" items do not offer the proper nutrition that ducks and geese need – and the act of feeding a diet heavy in bread and other empty carbohydrates can lead to severe health consequences and a variety of other problems.
Wild ducks and geese feed on a variety of grains and grasses, aquatic plants, and invertebrates, all naturally found in the wild. When eaten in combination, these foods are nutritionally balanced and provide everything a wild duck or goose needs to survive. In contrast, foods commonly fed to waterfowl in public parks, such as bread, crackers, popcorn, and corn, are typically low in protein and essential nutrients and minerals (such as calcium and phosphorus). While a single feeding of these “junk foods” may not harm waterfowl, it adds up! If everyone visiting a park “only” gives a few pieces of bread or crackers to ducks and geese, it quickly becomes the bulk of what wild waterfowl consume, and results in a variety of nutritional disorders.
Waterfowl in public parks are often admitted to wildlife rehabilitation centers with metabolic bone disease (MBD). Birds with MBD have incredibly soft bones and joints that are often malformed and fractured; these injuries are caused by an overall calcium deficiency in the body, which is linked to an inappropriate diet. Calcium also plays a crucial role in the formation of eggs/offspring, clotting ability, cardiovascular and neuromuscular function, and a variety of other metabolic activities.
Birds with MBD are often so malformed they cannot fly and become dependent on handouts, completing a vicious cycle. Affected birds are typically too weak to compete for food and defend themselves and are often the victims of aggressive attacks by other ducks and geese. One more problem with bread products is that this type of food expands in water -- and the stomach -- which gives ducks and geese an artificial feeling that they are full. As a result, these birds may not feel motivated to continue foraging on natural foods of higher nutritional value.
What You Can Do
Allowing ducks and geese to find their own wild, nutritionally balanced diet is best – for the health of waterfowl and the surrounding environment. Instead of feeding ducks and geese, consider collecting stray fishing hooks, lines, and sinkers.
