Anonymous5: you know birdo is a dude he is just trying to be a chick. There is a lot of controversy over him/her or what ever he/she is. There were even some comics that nintendo made (i think only in japan)were he got arrested for going into the girls bathroom.
Anonymous12: Until I hear Nintendo absolutely,positively and plainly say what sex "The Birdo" is my hair will remain a bird on this issue and like "The Yoshi" there are many Yoshis so even then I don't wanna hear it,it could just be a different Birdo,hell this one is red not pink like "The Birdo".
just enjoy the pic and move to the next thing
