The Duolingo Bird is a bird that has been alive for a few years. He is an idol to many and many memes have been created in his honor.
Firstly, the Duolingo bird is six feet tall and is an owl meant to symbolize wisdom and knowledge. Why he is green, nobody knows. His name is Duo, his gender is male, and his pronouns are he/him. He is supposed to be a coach who practices you while you learn. He gets mad when you don’t keep up your 2-day streak.
Duoling has had a lot of evolution since 2011. Here is a photo of how the duolingo bird has evolved.
