Today I walked through the forest again and then I saw a bird in the bush, it’s most likely an Eurasian blackcap bird, a male, because the females have an orange cap and not a black one. During my research I also thought it could be a March tit or the Willow tit, but now I am sure it’s the Eurasian blackcap because the others would have a black marking on the chin and there were some other differences. After I nailed it down to the three birds, I asked the Google image search and thought, yeah, this should definitely be the Eurasian blackcap (Sylvia atricapilla).
