Last week there were 26 to 22 of them working the pond as they rest and prepare to move northward.
It appears that they have already paired up. Some will stop in Yellowstone Park where the following were pictured last summer. They often swim around with their head under water searching for food. Once food is found, they will dive and may spend at least two minutes under water.
They are a striking black and white with brilliant red eyes.
I will continue watching them until they all leave the area. I wish some would stay and nest near Rexburg, but we do not have a large enough body of water to support them.
