Why do wild birds love Berlin?

Greenery
18% of Berlin are forests. 12% more are parks and gardens, including cemeteries. Raptors do have place to live.

Flat area
The highest hill in Berlin is slightly less than 121m tall (Arkenberg). The flatland makes perfect hunting grounds.

All the food
Raptors are doing quite well in terms of food here. Their menu comprises rodents, small birds, and wild rabbits.
