- In Alaska these Harlequin Ducks nest along some of our fastest flowing streams.
- This is quite unusual for ducks to nest in this type of habitat.
- What would be some of the advantages for doing this?
- These ducks feed heavily on aquatic insects while in these streams.
- They may do this by swimming upstream and turning over stones with the top of their bill and grabbing the insects that live under them.
- What other creatures in Alaska feed on and even depend on aquatic insects (in the aquatic stage)?
