The video is just precious.
That is good news that driver's slow down for birds. I do that here, where birds often linger in streets. If people don't slow down, birds often will die. There chickens with chicks around here that cross together. I think most people slow down for them.
I’ve seen this happen many times around here for flocks of geese, with or without goslings. And the big snots take their good old time too!
