Snow Geese and Snow

I decided to get out in the snow as my red birds were out of sunflower seeds.
Then I walked down toward Galla Lake which is about dry.
I think these are snow geese. They did not like me in the domain.
They all flew and scattered.
You can barely see them coming together down by the earth dam of the Lake.
In only a minute they were organized and returned toward me to fly on.
Then it was just me and the silent Lake once more.
