No, it's not The Birds by Alfred Hitchcock. It's the Helsinki Market Square, which, if truth be told, has too many uninhibited seagulls on the lookout for food. Some of them have been known to snatch food from someone who is eating it and is holding it in their hand.
The ground is cobbled, but fortunately level-surface. Easier to walk on it.
The pictures of the previous post are also from the Market Square.
