Night time temperatures drop below freezing. Autumn is waning.

Nothing says autumn quite like the flocks of geese flyng overhead. We saw this large assembly near Casselman. It was the first time I had seen snow geese and there were many mingling with the Canada geese. I imagine they fly in separate flocks, but they were all enjoying the pickings from this farmer's field.

It was a beautiful sunny day, the kind that celebrates the beauty of the changes as the plant life dries up and the last of the milkweed scatter its seeds. In this area, the trees have lost their foliage, exposing nests that once sheltered. These geese will be off soon, looking for more hospitable places, where food will be plentiful over the coming winter.
Geese honking overhead, heading north. We see great vees passing over and wonder at their tenacity and strength. They know what teamwork is, the vees changing shape as leaders change to give each a chance at riding the currents of the one before. Driving in the country we passed fields where the geese had stopped to rest and feed.
So much I don't understand about how the birds know their routes and travel so far. So much to wonder at.
Below is part of a flock we saw a couple of days ago - this is a back vee, part of a much larger flock. I love the sound as they go overhead.
