Like most of the cities in the World, Berlin has many urban animals and you can compare the birds with the land animals. Here’s an exampel:
Mouse = Sparrow (cute and picking all the little things to eat)
Rat = Dove (eating everything, dirty)
Fox = Crow (smart and bolt)
Squirrel = Blackbird (in alert and diligent)
and so on … So what do you think?
