Trumpeter Swan Diet
Trumpeter Swans have a primarily vegetarian diet, consisting of a wide range of aquatic plants. They consume species such as pondweeds, eelgrass, and duckweed, utilizing their long necks to reach and feed on these plants in shallow waters.
Although they are mainly herbivorous, Trumpeter Swans occasionally consume small fish and fish eggs as a supplement to their diet. This behavior is more common among adult swans and is believed to provide them with essential nutrients and variety.
During their juvenile stage, young Trumpeter Swans often begin their diet by consuming aquatic insects. This insect-rich diet helps strengthen their bodies and prepares them for the transition to a plant-dominated diet as they mature.
Trumpeter Swans have developed a unique underwater feeding technique. They feed by tipping their bodies and rooting beneath the surface of the water, twisting and pulling up vegetation from the bottom. This technique allows them to access submerged plants that other waterfowl may not be able to reach.
In addition to their aquatic diet, Trumpeter Swans adjust their food sources during the winter months. They forage on terrestrial plants, berries, and even grain crops to sustain themselves when their preferred aquatic vegetation is not readily available.
Trumpeter Swan Diet Overview:
| Feeding Preferences | Food Sources |
|---|---|
| Mainly Vegetarian | Aquatic plants such as pondweeds, eelgrass, duckweed |
| Occasional Fish Consumption | Small fish and fish eggs |
| Transition Diet (Juvenile Stage) | Aquatic insects |
| Underwater Feeding Technique | Tipping and rooting to pull up submerged vegetation |
