We learned of the migrating Snow Geese forty miles SW of Boise so we drove there in February. This photo is taken from a tower across the road from the game preserve where the geese are resting on their flight North. Annamarie is below, looking with her binoculars.
Zooming in on the middle area of what looks like styrofoam in the above photo, we see the actual geese.
Zooming in further, we see they are Snow Geese with one Mallard in their midst.
Driving home, we came across a flock of 200 or so Greater White-fronted Geese. Thiese were a new species for us.
