Dipper Singing and Feeding in Winter | Bob Armstrong's Nature Alaska

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.
