LOL, this comment proves that you like to interpret things to fit your own agenda or desire.
- I can also say Marco is a Phoenix and not a pheasant bird.
Bogard already explain it:
Red golden pheasants emanate from remote forests in the mountainous areas of western China where they are also known as red phoenix
Yamato is not really a dog too, but she has similarities to a one.
Same Luffy with not beeing a monkey.
So I don´t any problem with Marco beeing the "bird".
- Momotaro fought the Onis but Momo can't fight Kaido because he is too weak.
- Kaido is not an oni. He's a dragon.
Otama didn´t fought too, yet didn´t hold up Kaido to use her as reference, see?
Kaido is symbole of a Oni, he has a dragon fruit but he himself is a reference to a Oni.
In the moment when Oda bring up Momo above again, in this moment we see that he plan to bring the momotaro story.
Momo=Momotaro
Yamato=Dog
Luffy=Monkey
Marco=Bird
It going to happen most like.
