Here I have a hard time getting a message that has to do with aerials. I can hardly spot /identify the bird (duck?) - and my eyes really stick to the sign.
I have to agree. If I hadn't seen the entire series, or noticed the title, I don't think I would have recognized the (rather strange!) bird.
Ah. But what just occurred to me is that he does look rather like he's climbing over a sharp, pointed rock.

Something of a trick, for a flying creature...
