Vancouver Canada Geese feeding on the Mendenhall Wetlands

  • In winter these geese feed on the sprouts of Lyngby's Sedge (Carex lyngbyei)
  • Protein and nitrogen requirements of Canada Geese are highest in late winter and spring.
  • Why are the sedge sprouts more nutritious at this time?
  • As the greenery fades in the fall, a good deal of the nutrient value of the sedge moves down to the top of the root stock, where it is available for the initial growth surge in spring.
  • Geese search for and dig out this high-quality food, which provides a good deal of their conditioning for nesting.
