Birdo is a character in the Mario series. Her first appearance was in Doki Doki Panic, a Japanese game featuring her as the first boss. After its release in Japan, Nintendo of America remade it featuring Mario characters, but kept the enemies and bosses the same. This remake was known as Super Mario Bros. 2 in America, but called Super Mario USA when it was released in Japan later on.

Birdo later on appeared in many Mario spinoff games such as Mario Tennis. In most of these games, she was viewed as Yoshi's friend, but there is no real information on whether they have a relationship.

In Japan, Birdo is known as Catherine. Nintendo of America initially called him a guy like the Japanese games, but later changed it to a female after the Super Mario Bros. 2 manual described Birdo as "He thinks he's a girl and shoots eggs from his mouth." Birdo has been depicted as a female ever since. Super Smash Bros. Brawl states that Birdo's gender is indeterminate and refers to them as "it". In Japan it has been frequently stated that Birdo is in fact a male. She is voiced by Kazumi Totaka who also voices Yoshi.

Physical appearance

Birdo is a female dinosaur with a hot pink skin resembling a Yoshi. She has big purple eyes with three eyelashes. She has small, but pointed, claws on her hands and feet. She has three red spines on her back. She has a big red bow on her head, similar to Wendy O. Koopa's. She also has large diamond ring on her middle finger.


Birdo first appeared in Doki Doki Panic as an enemy early on in the game that could be defeated by using her eggs against her. She would appear again in the remake of the game, Super Mario Bros. 2. She later returned in the game Mario Tennis. She subsequently would appear in various Mario spin-offs, usually being a partner to Yoshi (presumably due to the similarities in appearance).
