Grün Berlin and NABU are collaborating on the development of an area on the edge of Tempelhofer Feld which used to be the “Alte Gärtnerei“.
The area has always been closed to the public, but while the area is being developed into, I think, a kind of environmental and/or nature education centre, NABU occasionally offers mornin tours there, since many winter birds can – in theory be seen there. Not many birds were active this morning, but we did keep seeing three goldfinches :-).
Nonetheless, it was an interesting hour led by a knowledgeable guide, and I will definitely go again if the opportunity arises.
This is the area on MapMyWalk.
In Anita-Berber-Park, in the way back to U-Bhf Leinestraße:
And almost home, in Oranienstraße, I think I saw a shorttoed tree creeper. It moved like one, but I would need to see its beak (should be quite long) to be certain.
