Finnish corner:
The pastry they are eating is called "karjalanpiirakka" - Karelian pie/pasty, which is made from rye flour crust and then porridge type stuffing. Stuffing used to be veggies or grain based, but nowadays it's almost always rice.
Very tasty with egg-butter.
Finnish ducks can be aggressive in getting that bread, if too used to humans, but still completely harmless. The flying rats on the other hand will steal your bread from your mouth, if they can.
The most common fowl here is mallard, "sinisorsa" - blue duck named after the blue-green hue of the male's head. It's also known as bun/baked roll duck, as it used to be common to feed them stale bread/buns, which they really loved, even if most pastries and bread is bad for them.
