Hallo,
Recently, I have been being paid daily visits von diesem feathery, dark, and quite fellow. Upon leaving my apartment heading to work, at around 5:30 AM this mysterious bird would be camping outside the building in a safe distance of approximately 10 meters, which he's so persistent to keep upon being approached.
Attempts to feed the little fellow have been futile, met with more cynicism on his/her part which is evident by the increasing of the distance from which he/she watches me.
Can any bird behavioral scientists amongst you lot propose a theory as to what could be the purpose this dark spy? Is this something birbs do often in Germany?
