Is Birdo a boy or girl?

[BP]

You can name a kid anything you want. Anything.

You shouldn't, but still.

Although, being that Birdo is transsexual, it is entirely possible Catherine is not the name on her birth certificate but one chosen for legal change. Since she doesn't have a made-up/unisex name in Japan. Even in English we have Superstar Saga where she tells Popple that she doesn't want to be called by the masculine-sounding "Birdo," wanting to be called "Birdie" instead.

Catherine is totally his drag queen name. His Japanese bio (if you read the link) also says he likes to be called 'Cathy'.

He enjoys candle-lit dinners and long walks on the beach.

Wouldn't put it past him, honestly.

MATURE AUDIENCES ONLY FOR THIS POST
This explanation is not satisfactory. If there's a big hole that eggs are coming out of, xe doesn't just "think" xe's a girl.

Birdo snouts could be cloacas, which would explain why every Birdo we've seen has one (and maybe also why someone thought they resembled birds).

[ShadowBrain]

Question, before I forget: is "xe" unpronounceable, or do you say it like Chekov saying "the"?

[Weegee]

I pronounce it as "zee" or "it", depending on how badly I want to offend the other party.

Despite all the official media, I myself find it hard to determine Birdo's gender. My 7-year-old brother actually believes Birdo is a boy! Unless I want to talk about the topic though, I go around calling Birdo an "it" to play it safe. But when I'm wanting to talk about it...

I believe in the possibility that older American media and present-day Japanese media calling Birdo/Catherine a boy. But I also believe Birdo can be a girl too, especially if we're talking about Yoshi's love interests, because I know not everyone can be accepting for such a relationship if the two were boys, you know what I mean? I wouldn't care either way, don't get me wrong, but that doesn't mean EVERYONE else thinks the same as me.
