Birdos are brightly-colored, large-snouted creatures from the Super Mario series. In Super Mario Bros. 2, only one Birdo is shown to exist; she is named after her species, and is later developed into a major character in numerous spin-offs. The Super Mario Bros. Super Show! is the first source in which other Birdos appear. Other Birdos later appear as spectators in various Mario titles, starting in Mario Power Tennis, and make playable appearances in Super Mario Strikers and Mario Strikers Charged.
Super Mario Bros. 2
Birdos are first encountered serving under Wart, including the main pink Birdo known as "Birdo". There are pink, red, green, and grey varieties of the species, each with different abilities. The Birdos serve as bosses in the first and second levels of six worlds. The grey only appears in the main game, while the three other varieties appear in both the main game and the remakes. One pink Birdo appears as an enemy in World 4-3, a green Birdo serves as the boss in World 6-1 and 6-2, four red Birdos appear before a boss battle, one in World 5-3 before Clawgrip's fight, another in World 6-3 before Tryclyde's fight, and two in Wart's Castle, one of which spits out the key once it is defeated.
The Super Mario Bros. Super Show!
Birdos appeared in various episodes of The Super Mario Bros. Super Show! as part of the Koopa Pack. In "The Adventures of Dirk Drain-Head" Bowser claimed to keep his Birdos in cages lined with Baroness Blue Blood comic book pages.
"The Bird! The Bird!
Birdos first appeared in the episode "The Bird! The Bird!", where a female mistakes Toad for her baby & unwittingly kidnaps him. On the way to rescue him, Mario, Luigi, and Princess Toadstool found Cheepy encased in ice & started a fire to thaw out the baby Birdo. Meanwhile, Cheepy's mother takes Toad out into the open skies and lets go, sending him into a free-fall. Rather than plummeting to his doom, however, Toad managed to land safely by using his cap as a parachute, after which the group returned Cheepy to his mother. She later repays the heroes by helping them stave off an attack by King Koopa, carrying Toad while he drops vegetables on the soldiers of the Koopa Pack, thus forcing Bowser to retreat.
"Butch Mario and the Luigi Kid"
Regardless of the defeat, Bowser continued to use Birdos in the Koopa Troop. In "Jungle Fever," King Koopa utilized several of them as guards. This proved beneficial to his cause. One Birdo was able to use its egg to bring down an Albatoss carrying Mario, Luigi, Princess Toadstool, and Toad. Despite the efforts of the Birdos, however, King Koopa's plan failed.
King Koopa assigned three Birdos to act as the guns of his three State Troopa cars by firing eggs at the Rebel Fort while perched atop the vehicles. After the Mario Bros. arrived, Bowser decided to use the Thunder Birdo to attack the fort. Thunder Birdo was driven in on another vehicle, controlled by Mouser, where it proceeded to attack the fort with a gigantic, explosive egg. Afterwards, Bowser used normal Birdo fire until a rebel force, which included Mario, Luigi, Princess Toadstool, and Toad, left the fort using a tanker full of spaghetti sauce as bait. During the chase that ensued, the three Birdos were defeated by Luigi's Bob-ombs after attacking Mario and Toadstool. After the two regained control, they saw the approaching Thunder Birdo. Peach climbed on top of the tanker armed with a bag of Bob-ombs. When Mouser approached, the princess hurled the bag into the snout of the Birdo. Thunder Birdo swallowed the Bob-ombs, and their explosion defeated her.
"On Her Majesty's Sewer Service"
During the events of, "On Her Majesty's Sewer Service," Bowser hired an enormous Birdo with dragon wings. A K was emblazoned on its chest. Koopa, Mouser, Tryclyde, and Koopa Troopa embarked to rob Spy Land's Coin supply from Fort Hard Knox, but were pursued by Mario and Luigi in the Spymobile. King Koopa, after several failed attempts to destroy the vehicle, called for the Birdo to lift the Spymobile from the road. The Birdo deposited the brothers in King Koopa's lair.
"Escape from Koopatraz"
In "Escape from Koopatraz", Bowser included one in the jury for the trial of Mario, Luigi, Princess Toadstool, and Toad. The Birdo deliberated the decision with the three other members of the jury, until King Koopa threatened them with a Piranha Plant. They quickly condemned Princess Toadstool and her friends as guilty.
Nintendo Comics System
As seen in the Nintendo Comics System comics "Bedtime for Drain-Head" and "Betrayal Most Proper", after losing control of the Mushroom Kingdom, Bowser employed Birdos as castle guards. Mario came to grips with these guards on two occasions. Under the delusion that he was Dirk Drain-Head in "Bedtime for Drain-Head," Mario entered Bowser's Castle to save Toad. After laying waste to a large number of enemies outside of the castle, a Birdo blocked Mario's path as he tried to enter the castle, shooting eggs at him. However, Mario quickly picked them up and threw them back, defeating this Birdo as he had defeated the Birdo in Super Mario Bros. 2. The second occasion, in "Betrayal Most Proper," Mario and Toad were attempting to rescue Wooster when they were attacked by Birdos in Bowser's Castle. When Mario and Toad's movement was impaired by a conveyor belt moving in the opposite direction they were running, the Birdos began firing eggs. Rather than defeat the Birdos, the rescuers simply ran onwards.
Mario Tennis series
Many different colored Birdos appear as background NPCs in cutscenes in Mario Power Tennis for the GameCube, most notably the red Birdo in Bowser's trophy acceptance cutscene.
Mario Strikers series
Soccer is the one sport that a substantial number of Birdos participate. In the original Super Mario Strikers tournaments, teams of Birdos can be selected by certain high-profile captains to help them achieve victory. When compared to the other species involved, members of the Birdo species are the most aggressive, scoring the hard hits against opponents necessary in the sport. The events are also a huge draw for Birdo spectators.
The next iteration of the sport, Mario Strikers Charged, also draws much attention from the Birdo species as a whole. Once again, multiple Birdos compete as sidekick players, this time breaking away from all Birdo teams and playing alongside other species. And again, Birdos are one of the many species filling the stadiums.
Mario & Sonic at the London 2012 Olympic Games
Birdos as well as the character Birdo appear in Mario & Sonic at the London 2012 Olympic Games. In the game, several colored Birdos serve as goalies in the Football event and a partner to Birdo in the Badminton Doubles in the London Party mode.
Aside from the Mario Strikers participants, there is one Birdo known to participate in many sports competitions. Birdo made her sports debut in Mario Tennis and continued to participate in the competitions of Mario Golf: Toadstool Tour, Mario Kart: Double Dash!!, Mario Superstar Baseball, Mario Hoops 3-on-3, Mario Kart Wii, Mario Super Sluggers, and most recently Mario & Sonic at the London 2012 Olympic Games.
Peaceful Birdos have made appearances in the audiences of many sports and racing games. They first appear at Peach Dome in Mario Power Tennis, and later attend Mario Stadium in Mario Superstar Baseball. Their most recent appearances are in the stands of various tracks of Mario Kart Wii and Mario Super Sluggers. They reprise this role in Mario Sports Mix, in which they can be seen splashing in pools and waving in the background of some courts such as Koopa Troopa Beach, Daisy Garden, and Bowser Jr. Blvd..
In Super Mario Chess, Birdos appear as knights on Bowser's team.
