Birdie[2], also spelt Birdy[3][4] and known as Kotori-san (小鳥さん[2]) in Japan, is a character in the Sonic the Hedgehog series. He is the blue bird that Amy Rose befriends in Sonic Adventure. During the game's story, he is being chased by Dr. Eggman for the cyan Chaos Emerald in the pendant hanging around his neck.


Before the beginning of Sonic Adventure, Birdie and his family were apparently captured by Dr. Eggman, to be used as organic batteries in his robots. Amy first encounters Birdie in Sonic Adventure when the bird slams into her after escaping from Eggman's Egg Carrier. Soon Birdie is pursued by ZERO and Amy vows to protect him. After getting separated from Sonic, Amy and Birdie get kidnapped by ZERO and are put in a holding cell aboard the Egg Carrier. Eggman orders E-102 Gamma down to the cells to retrieve Birdie from Amy, and as the robot approaches, Birdie flies up to Gamma's face, appearing to almost recognize it. Unknown to Amy, a member of Birdie's family was inside Gamma. Because of this, Gamma reneges against his programming and releases the two.

After Amy and Birdie escape from the Egg Carrier, Amy discovers the picture of Birdie with his family in the locket around the bird's neck. Amy decides to help Birdie find her family. They eventually come back to the Egg Carrier where they do find Birdie's family, recently released from their E-series hosts E-101 Beta and E-102 Gamma when the robots destroyed each other. Just as they were about to reunite, Birdie is shot down by ZERO. Angered, Amy fights and destroys it. Birdie is not seriously hurt by ZERO's sneak attack and is able to fly off with his family.

During the course of Sonic Adventure, Birdie always appears flying by Amy's side, but will not appear while she is in the Chao Garden or in Sonic Adventure DX: Director's Cut's Mission Mode.

Birdie's gender was changed to male in the English version of Sonic Adventure for unknown reasons. While the Japanese version also makes it clear that Birdie and the other two birds are brothers[2], this is never mentioned in the English version - only referring to the other two birds as "family". The Sonic the Hedgehog Encyclo-speed-ia, however, claims the two birds are Birdie's parents[3].

In this series, "Birdie" is used to refer to the pink Flicky that was inside of E-102 γ.[5] Birdie was there when Sonic shattered the Paradox Prism, causing the Flicky to divide into multiple versions across the Shatterverse.[6] Later on, Tails Nine creates a robot doppelganger of Birdie named Grim Birdie.[7]
