It was a relatively sunny day so I started by going back to Natur-Park Südgelände, this time with more time to have a good look around, and I did indeed see two birds that I had never seen before (in my defence I will say that I have not been that interested in birds for that long ……): the two bullfinches (DK: Dompap, DE: Gimpel), and the tiny, elusive (hence the bad photo) long-tailed tit (DK: Halemejse, DE: Schwanzmeise). It was quicker to identify them than to find out what they are called in Danish. Google Translate is totally clueless in that regard.
I then took a swing into Friedhof Steglitz, past S Friedenau and finally took a quick look at Kleistpark. The route on mapmywalk here.
