>>29261720I hate you so fucking much anon. So much. You're a detestable person. Your 'concept' of how they're related is basically bullshit that has no bearing on how gamefreak chose to design this fucking line. It was a case of 'surprisu' and not much else.
This 'established trope' you speak of regarding regional birds is also kind of bullshit because no other regional bird tries so unflinchingly hard to be a real life species. They all look hybridized to a degree with mixes of raptoral and passerine traits. However what they all have is running thematic elements through them (pidgey: striped headcrest, starly: facial marking/crest, pidove: prominent cere that developes into other facial ornamentation, fletchling: 'flaming arrow' concept/ arrow fletching tail) and also their designs just intuitively fit together better than this one, where body shape changes far too radically. Also you could argue that the reason the regional birds seem to change species is because they go from cuter, smaller and passerine in appearance towards raptorial adults. Real life raptor birds do actually look kinda cute and fluffy when they're younger.
You're really fucking reaching abd presuming so much to think YOUR idea is exactly what gamefreak had in mind when that probably wasn't the case. I'm trying to argue that there really is no theme to this line but 'surprise' and that they have prominent beak aspects. Furthermore the other main criticism is how the toucan is barely barely stylized.
