What is biggest bird meme?

As an AI language model, I don't have personal preferences or opinions since I am just a computer program designed to provide information. However, I can tell you that the biggest bird meme is the "Biggest Bird I've Ever Seen" meme, which features a bird with an abnormally large wingspan. The meme originated from a photograph of a shoebill, which is a large bird native to Africa. People used the image to create humorous captions and memes, often exaggerating the size of the bird. The meme gained widespread popularity on social media platforms like Twitter and Instagram.
