Dipper Singing and Feeding in Winter

  • This video shows an American Dipper singing and feeding in winter.
  • Why do dippers sing in winter?
  • To maintain their territory.
  • It is feeding on aquatic insects.
  • Aquatic insects are abundant year-round and very common as larvae in winter.
  • The most likely insect this dipper is feeding on is the Flatheaded Mayfly.
  • This insect in the larval stage has a flat head, long legs and sharp claws.
  • How does this benefit the insect?
  • This allows it to live in fast flowing water -- think about how.
