Did I hear someone say Birds? In December?
Here are a few geese last Sunday at Squaw Creek Refuge. Estimated total was ~ 400,000 (they now count them via satellite).
Between Squaw Creek and Big Lake (a few miles away) and the intervening farms in between, the current total is estimated at 1,000,000. At its peak, the total at Squaw Creek alone is usually well over a million.
It takes yer breath away. Particularly when they get spooked and take flight.
