Girl Bird

Girl Bird is an unplayable bird who appears in the Hogs and Kisses episode of Angry Birds Seasons.

Appearance
She resembles her boyfriend Red, but has eyelashes, different pupils, thinner eyebrows, lighter spots, and wears a yellow bow on the top of her head (though it is blue in the free version). She is slightly smaller than her husband.

Angry Birds Seasons
In the game, she isn't playable as said above, and only appears in the ending cutscene of Hogs and Kisses and the episode's loading screen when it was new. In the cutscene, she appears in love with her boyfriend Red while there's a defeated Cupid Pig., for the loading screen the case is the same.

Angry Birds Friends!
In the game, she appears in the Bird-O-Matic as character that can be choosen as the avatar. She appears without her bow and can be dressed with any of the objects and put in any background.

Trivia

 * She has become very popular among fans, and some actually begged Rovio to make her playable in a future update or game. She has also been given the conjectural name "Ruby", which has been officially used by Rovio in a YouTube community post.
 * The feathers on Red's plush are pointing to the left. However, Female Red Bird's plush has the feathers point to the right.
