A Fish and Bird Mixing Zone | Bob Armstrong's Nature Alaska

A Fish and Bird Mixing Zone is a video taken along the Mendenhall Lake in Juneau, Alaska.
The value of these clearwater streams entering a glacial lake appears to be important for both fish and birds.
Possible reasons include: 1. The stream water is warmer than the water in the glacier lake which would provide a better habitat for aquatic insects and in turn, attract salmon and Dolly Varden young to feed on them. 2. The aquatic insects, especially after emerging, would attract songbirds to feed on them. 3. The stream no doubt moves various plant seeds from the forest into this zone which provides food for seed eating birds.
A study of this type of habitat could be very important. These areas, perhaps, should be protected from human disturbance.
