One on 28 September with VHS Pankow in Freizeitpark Marienfelde, and one on 29 September, found in Umweltkalender, in Britzer Garten.
I am finding it a little bit strange that they would organise the one tomorrow on the day of the – fiftieth! – Berlin Marathon. For anyone living inside the route, not to mention those who live north of Berlin and somehow have to make it across the city, it might be difficult if not impossible to get there, since many bus routes are suspended and many streets blocked off. (And no, I am not complaining about the marathon like so many others – it is a feast, if you ask me, and it is one weekend each year, so either just stay at home or go out and enjoy the spectacle and stop whining).
Anyway, both walks were very pleasant. In Marienfelde, we saw a heron and a largeish flock of long-tailed tits, as well as a buzzard and a kestrel.
In Britzer Garten, we saw five jays at the same time in one tree, several types of woodpecker and tit, and a sparrowhawk. On my way out I saw a bird of prey being escorted to the nearest exit by two crows.
