My partner and i have looked through some books but are still not 100% sure . It seemed to act strange with it moving it's head slowly from side to side , Looking like it was doing everything in slow motion . The last 2 suggestions are just random .

What species is it? European Greenfinch
Eurasian Siskin
European Serin Suggest another species?
