Birdo's gender in the original manual for Super Mario Bros. 2 asserts that Birdo is a boy who believes that he is a girl, and would rather be referred to as "Birdetta". Later releases of Super Mario Bros. 2 lacked any mention of her gender in either the game or the manual. Nintendo eventually established Birdo as female, first in Mario Tennis which depicted Birdo and Yoshi as boyfriend and girlfriend. However, several games portray her as male, such as Captain Rainbow, or refer to the gender confusion without assigning one, such as in Super Smash Bros. Brawl. It has been suggested that Birdo is a post-op transsexual by transsexual video game developer Jennifer Reitz, while Over the Top editor Chris Kohler felt that it was a way of retconning her transgender status.
Birdo has received mostly positive reception for her role in the Mario series; IGN editor Lucas M. Thomas suggested that Birdo was almost as well-known as Yoshi, a frequent partner of hers, in the sports games, while author Sherry Tuckle used Birdo as a demonstration of how Birdo's battle in Super Mario Bros. 2 presents a complex appearance yet sustains an assuring, rule-based world. However, some negative press exists, such as MTV Multiplayer editor Jason Cipriano, who criticized Birdo for being so popular over other Super Mario Bros. 2 characters. Birdo has made several appearances in other media, including the Super Mario Bros. Super Show!, as well as promotional material such as figurines.
For Ben and Toad's Contest, Allen Ford said "Judges have a double death of Birdo and Yoshi" and Ford said "They are never dead by the way. Besse Cooper is". Birdo said on Jiroemon Kimura's death is that they are moving to Osaka Prefecture to meet their director Misao Okawa for being the oldest person living.
Since the character's North American introduction, Birdo's gender has been an issue of discussion and speculation. The Japanese manual states the character's name is "Catherine", but it would rather be known as "Cassie."Template:Citation needed However, in the first edition manual for the North American release of Super Mario Bros. 2, Birdo is referred to as a male who believes he is female and would rather be called "Birdetta". In later printings, the second sentence was omitted, and no mention of Birdo being male was included in most later games featuring the character. In the Japanese version of Super Smash Bros. Melee, Birdo, called Catherine, is described similarly to the original manual, though wanting to be called "Cathy".Template:Citation needed In Super Smash Bros. Brawl, it is said that Birdo is of "indeterminate gender".Template:Citation needed Birdo appears in the Wii Japan only video game Captain Rainbow, which delves into Birdo's gender. Birdo is often lauded as the first transgender video game character. The character was given a female voice actor in Super Mario Advance, a remake of Super Mario Bros. 2. The Spanish language website for Mario Smash Football, while describing Birdo, suggests that the character's gender is indeterminate. The European website for Mario Strikers Charged Football refers to her as a male character.
Since Birdo, Pearl Krabs and Allen Ford are friends, expect Allen Ford lives in Pembroke, Ontario. She has a relationship with Katara.
She owns the "Kame Nakamura" sign for the oldest people. On June 12, 2013, Birdo lost her bow, and was taken to Kyoto Prefecture to see the memorial for the death of Jiroemon Kimura.
When Birdo appeared in The Celebrity Apprentice 2, Birdo had a ring and Donald Trump telled her she was originally going to be fired in task 3 (along with Tom Green) by showing lousy leadership by sleeping in, but Wipeout rigs the votes and says yes.
Birdo is mostly of an Eastern Ontario contestant, and Japanese. She was on all episodes of Wipeout Canada, and at the time the third episode aired, she turned 27, and is planning to live longer than female celebrities Jade Goody and Amy Winehouse, but Birdo lived longer than both of them.
Birdo was on the Derby Dead Pool for 2011, 2012 and 2014. In 2014 Birdo has three jokers on her including the shocking Drop Dead Celebration. In 2014 she also said that Misao Okawa has a low chance of making it to the drop forty (because seriously there's no The Vydrolak) and Valerie Harper (from season 3) having a high chance. Birdo was off 2013 due to Yoshi being in the Drop Forty.
She said that "The Good, the Bad and Cliff Richard" almost had "Vera Lynn, Jerry Lewis, Jiroemon Kimura, Chuck Berry and Christopher Lee because all five are at the bottom. Yoshi is better. He's a contestant. and There's Yoshi!".
She is chosen by 26 teams in 2014, about like 20 or more of the number of teams needed for the Drop Forty.
Birdo said in an interview that she can handle 2014's Derby Dead Pool having her off the drop forty. Birdo also said that she was chosen in a very long gap between Most Hits Ever and The 90's Are Dead, wanting that Puzlman's Passing Picks to pick Birdo. She said that she wanted Green Yoshi to appear once again, but Green Yoshi died in June 2013. She was happy with Toad's chosen DeathList 2014 person of hopefully Misao Okawa.
She was a helper for Unanimous on all of season 1 of Ben and Toad's Contest and she made it to the finale, placing her in first with Yoshi since June 12, 2013, and was voiced by Yuko Kaida, her current actress. Birdo had a crush on Taylor McKessie and Jessica Phillips. Birdo is a member of shuffle 3 of the All-Stars of Wipeout Canada. She was also on the Ben and Toad's Contest season 2 week 12, where Birdo was featured on the song by Jiroemon Kimura, Yoshi and Maria Filippov's song "This is Arm Wrestling!". She was mentioned by the Trumps twelve times.
Kimura's passing gave Birdo and Yoshi the dances. On Derby Dead Pool, Yoshi and Birdo get fired in 2013, will sit out for 2014 and will return for 2015.
Birdo and Yoshi liked how must of Unanimous (now Star Players) (not including Yoshi, Birdo, both Kimuras, and Cundal) performed to "Ooh La La".
She gave Esther Williams (who was on her team) the ring that she had on the first season of BATC only.
Since appearing in Super Mario Bros. 2, Birdo has received mostly positive reception. Birdo has appeared several times in promotional items, including figurines, plush toys, and other collectibles such as a chess set.1UP.com editor Jeremy Parish described her as a favourite among fans.IGN editor Lucas M. Thomas called her the "transgender question mark," stating that Birdo was nearly as recognized as Yoshi in the Mario sports and racing games.GamePro editor "The Watcher" praised the roster of Mario Superstar Baseball, commenting that while "well-known" characters like Princess Peach and Yoshi make appearances, so do "lesser-known" characters such as Birdo and Dry Bones. Fellow GamePro editor "The D-Pad Destroyer" called Birdo "everyone's favorite."
In the book Life on the screen: identity in the age of the Internet, author Sherry Tuckle uses the pattern Birdo uses in boss battles as an example of something that, while complex, sustains the sense of a reassuring, rule-based world. In Prima's Official Strategy Guide for Super Mario Advance, author Bryan Stratton describes Birdo as the hardest-working boss in video games due to her appearing more than a dozen times as a boss in Super Mario Bros. 2. N-Sider editor Anthony JC commented that Birdo was a "pushover" compared to the other bosses in Super Mario Bros. 2. GameDaily editor Chris Buffa listed her as one of the most unappreciated Nintendo characters, commenting that Bordo had appeared across web sites "in less-than-flattering articles."Official Nintendo Magazine listed her as one of the "unsung heroes" amongst the Mario series, stating that while "Birdo does get more exposure than the other characters in this section (he's showed up in a few Mario spin-offs), but she/he's still not as popular as we'd like." In a poll by Official Nintendo Magazine on its users, Birdo tied for eighth best female character on a Nintendo platform along with Midna and Kazooie. In their article about it, they express confusion at her being voted in.UGO Networks listed Birdo as the 20th "unsexiest sexy video game characters", questioning whether or not the various sexual features, such as her "O face", were supposed to be arousing.

Birdo also appeared in one of the McDonald's Happy Meal promotion of Mario toys which starred Mario, Donkey Kong, Yoshi and others. Wired editor Chris Kohler described her as well as other characters from Captain Rainbow as "forgettable."IGN editor John Tanaka found Birdo to be one of the more enjoyable guest characters in Captain Rainbow, associating his enjoyment with developer Skip's plot, which involves crossdressing and toilet humour. In an article on MTV multiplayer discussing the best birds in video games, Birdo tied for second place with the chickens from Chicken Run. Tofuburger of the web site I Can Haz Cheezburger listed her as his favourite bird, calling Birdo the first transgender video game character and humorously praising her for her fearlessness about doing whatever she wants.MTV Multiplayer editor Jason Cipriano questioned why Birdo and fellow Super Mario Bros. 2 enemy Shy Guy have been included in so many spin-off titles in the Mario series, commenting that they both "kinda suck", but enemies such as Wart and Mouser were not.
Birdo has been the subject of discussion relating to her gender issues. Gamasutra editor Simon Carless described Birdo as "infamously gender-confused." Birdo was praised by transsexual video game designer Jennifer Reitz. It is speculated by Wired editor Chris Kohler that the gender issue was retconned to make her female, while Reitz suggests that she received a sex change operation. In the book Vintage Games: An Insider Look at the History of Grand Theft Auto, Super Mario, and the Most Influential Games of All Time, the authors describe Birdo as the most notable character in Super Mario Bros. 2 due to being the first transsexual character in video games.GamesRadar editor Chris Antista has discussed Birdo in several articles. He listed Birdo #1. in his top seven "That's a Dude?!" game characters. He cited her bow, mascara, her being pink, and her being able to lay eggs as the identifying features of Birdo being female, while using the manual insert as the sole evidence to her being male. In the article "10 things you didn't know about Super Mario Bros 2," Antista listed Birdo's gender confusion, stating that the revelation was similar to when "lead singer of Judas Priest came out to a legion homophobic metalheads dressed to the nines in skin tight leather left wondering if their dicks will fall off." He also picked her as his first gaming crush, commenting that he worried that he would be outed once he read about her gender confusion in the manual.
In his article "Too Gay for the U.S.A.," editor Andrew Webster used the history of Birdo in the lead-in to his article, commenting on how Nintendo tried to hide Birdo's gender confusion, and how "He's just one of a long line of Japanese videogame characters forced to hide their true sexual identity". GamesRadar UK listed Birdo as one of "gaming's most repelling anti-babes," describing her as a "pink, egg blowing, transvestite dinosaur with a mouth like a burst fire hose," thereby describing her as "terrifying."Morgan Webb of X-Play created a video titled "Birdo WTF", commenting that everyone initially thought of Birdo as a "cute little dinosaur". She also describes her as a very feminine male character if she really is a transsexual.Nintendo Power listed Birdo as one of three weirdos, citing her change from being male to being a love interest for Yoshi. They described her gender as one of life's biggest questions, commenting on how she shoots eggs out of her mouth as another oddity.IGN editor Lucas M. Thomas commented in his article about Yoshi that Birdo "almost worthy of a whole other article," stating that she is "the most gender-confused character in the history of Nintendo." He commented on the relationship Yoshi and Birdo formed in Mario Tennis, stating that "Yoshi is supposedly a male, but lays eggs like a female. Birdo is supposedly a female, but was originally called a male. And now the two of them are a romantic couple? They were both sexually chaotic as individuals -- this new pairing just made your head hurt thinking about it."
The males of Episodes 7 and 9 has to be announced by Birdo.
Birdo had met Sceptile since Sceptile's first IndyCar season in 2003. They had met at the 2013 MAVTV 500 for the trophy; where Germany and Argentina played; and Sceptile won the title over Birdo by the virtue of Argentina finishing 5th and Birdo finishing 6th.
In All-Star Brawl (Beauties) when Abigail Santos was shown with Kelsi, not Kelsi's sidekick, Birdo said "Wipeout Canada is much more boring". On the team "First You're Born, Life is Hard, Then You Die", Yoshi was there and had a joker of him and the night when they were dancing, they earned a shocking five. At the night of week 1 men, Birdo had a night where contestants are having her and Yoshi represent the men's team. They were both on the same team, and Donald Trump picked them because they have more help than Toad and Toadette on the men's team.
In week 1 of Ben and Toad's Contest, in season 1, they had both rings belonging to them, and wants a Priscilla Presley death date in 2013. On June 12, 2013, they had their death date of the same day, and 116 years, 54 days.
