The kettling activity is because most of the rivers are still pretty open,
and there is no snow cover on the ground. They are normally fishing from
the trees near the dam and dont have much open river. They are likely using
the trees for rest at night, and then spreading out to search for other
food sources during the day that would be easier than fishing. Warmer temps
also slow their metabolism allowing for more "playful flight" opportunities
than they would normally have, as they aren't burning as many calories
trying to maintain body temperature. The large numbers are likely because
of plentiful dead geese and other migratory water species above the dam
from hunting and avian flu. If we get snow cover, and colder temps to
freeze the rivers up, they will go back to their normal fishing close to
the dam with many staying right below the outlet all day. But forecasts
don't have any long stretches of cold weather in the next 2-3 weeks, so
this behavior may continue for a while.
