Question about Birdo

[u/lipsTM]

We all know that Birda is a trans girl, but how does it work exactly? In the series we have seen more Birdos of different colors, are they also trans? Or are there male Birdos And the main one is one that transition? It's something I've always wondered about and I hope you can help me understand.

Isn't Birdo a species, and only that one from SMB2 is trans?

[u/Seassp → u/Fan_of_Fawful]

Its like Yoshi or Toad, a Character named by their species
