Quick Answer
Mallards in flooded areas prefer to feed on aquatic plants, such as duckweed, and invertebrates like snails and leeches. They will also eat small crustaceans like crayfish and aquatic insects. These food sources are abundant in Arkansas timber mallards' habitats.
Food Source in Flooded Areas
In flooded timber mallards’ habitats, aquatic plants provide essential nutrition. Duckweed, for instance, is a preferred food source due to its high protein content. A study in Arkansas found that duckweed makes up to 70% of a mallard’s diet during peak flooding periods. Mallards will also feed on other aquatic plants like water lilies and algae.
Feeding Behavior in Timber Mallards
Timber mallards exhibit unique feeding behavior in flooded areas. They tend to feed in shallow water, often less than 6 inches deep, where aquatic plants are abundant. Mallards use their powerful beaks to root around in the sediment, searching for invertebrates like snails and leeches. During periods of heavy flooding, these mallards will also venture onto wetlands and agricultural fields to feed on grains and small invertebrates.
Importance of Invertebrates in Mallard Diet
Invertebrates like crayfish and snails are crucial components of a timber mallard’s diet. These animals provide essential nutrients, including calcium, which is vital for eggshell production and bone growth. In Arkansas, research suggests that invertebrates make up to 20% of a mallard’s diet during the breeding season. By consuming these invertebrates, mallards are able to maintain optimal health and reproductive success in their flooded habitats.
