There is a geese crossing in a shopping/office complex near me. The folks who built the complex were very nature friendly. They improved the pond and saved much of the woods surrounding the complex.
When the geese decide to parade from the pond (behind the white fence) across the complex entrance and into the woods a horn sounds and the stoplight turns red immediately. I think there is a motion detector at goose height that sets this all off.
One goose will always wait at the fence until everyone is safe.
I was several cars back and couldn't catch the crossing but I did catch the crossing guard.
