With speed-talking and -walking Benedikt Jackowski, Freilandlabor Britz, as usual extremely informative walk. Saw many flocks of small birds, mainly Chaffinch, Chiffchaff and Goldfinch, as well as the usual suspects pigeons and crows.
Also saw several of the usual dramas in the air where a Kestrel was being mobbed by one or more crows, and then, new to me, a Kestrel calmly and completely ignoring the BS from a crow that was edging closer and closer and after about five minutes gave up and flew away.
