One day in my local park and I noticed a family of crows, The Gracks, flying around and coming down to land at a particular spot. I wondered what they were up to so I stayed put and watched them for a while. Was it food I wondered? But no, I realised that this was a game! The crows would take off, circle for a while and then all three would chase down the wind and attempt to land at the same spot. They did it over and over, shrieking and cawing as they came, I swear they were laughing. I think these were lessons in fast landings for the kids. Crow school does look like fun.
