Cows can get very curious sometimes.
It is the bottom back part of a truck, a Saurier, which is one of the few, if at all the only Swiss manufacture of motors.
It is the very first time that I managed a close up of a bird in flight, but it was a big bird. I think it was actually one of our storks from the colony near us. I was standing next to a field and three of them came flying and they are big birds. This was the last in the row and I just manage to take the photo. It got a little dangerous as I had to move to one side.
