Hi,Manfred! A blackbird with a yellow beak is a girl blackbird. One of these flew to us. It (She) wanted to eat. The titmices were pecking the seeds. It(She) didn't like the sunflower seeds. I didn't manage to treat her. I made a bun with cottage cheese. The sly magpie ate this delicacy immediately.So I failed to tame the thrush. I failed to become a bird tamer. Many parameters ought to be overcome to become a successful tamer, and not only of birds.
Yes, dear MarBess, the color of the beaks of male blackbirds is much stronger than that of females, and the males have a beautiful, jet-black coat. It's the same with birds as with humans: the men are much more beautiful than the women! :-)))
I often talk to my female blackbird, and she hops around me. But when I then extend my hand, she moves further away from me again. I'm not a successful tamer too.
