How do birds help disperse sedge seeds to new wetlands?

Birds contribute to the dispersal of sedge seeds primarily through a process known as epizoochory. Because sedge seeds are small, they can become embedded in mud that adheres to the bodies of waterfowl and other terrestrial birds. As these birds travel between different environments, the mud—and the seeds trapped within it—can be transported to new wetlands, facilitating the spread of the plants to new locations.12
