Every fall we get a few days where robins are abundant and tear around as if they've completely lost it. It's when I get phone calls about all the robins in the yard.
Today was one of those days with crazy robins. There were many robins in the area. They chase each other and you'd think they are acrobats by their flying. At this time it's common for robins to hit your windows. It is fall migration. They are feeding heavily to fatten up and have spare energy. We will get several rushes of robins. Robins nest on the Arctic coast so we have robins go through from much further north. I would think our local robins have gone south a few weeks ago.
In spite of all the emphasis on fall migration, we have quite a few robins who stay with us all winter. I've seen robins in every month of the year. We usually get robins counted in the Christmas bird count.
Now added to the fun today were the black birds. We usually have a day or two with masses of blackbirds. Trees are full of blackbirds and they fly as a flock. I can spend a whole day watching black birds from my windows.
So I'll be watching for more robins and blackbirds tomorrow.
Tell me if you have large flocks of birds going through the area.
