Off the thread topic slightly, but has to do with diving ducks (birds).

As the fish returns increased on the Sky, so did the number of birds feeding on them, lots of cormorants, and other diving ducks, plus the number of eagles increased, feeding on both fish and birds. As the fish returns started dropping off the eagles started feeding on the ducks more often. I now can watch eagles target diving ducks for lunch.

I've seen 9 or more eagles sitting in the trees and the ducks hiding under brush and logs at or near the bank, you can't even scare them out from under their hiding places when eagles are around. Eagles even land on the log above the ducks and hop around trying to drive them out, when one tries to escape the eagle makes short work it.

The eagles will also circle above the ducks, with the ducks diving to avoid being grabbed. The eagles just keep circling tighter and closer until they're eventually right above the duck when it surfaces, then its one less duck.

Chums had been a major food source for the eagles, but with roe being very popular in Asia we just don’t see many in the river now.
