"The Bird" was one of the ideas considered for Twitter's original logo. That is, the extended middle finger gesture known in North America by that name. Other ideas, however, hewed closer to traditional images of birds.
That, at least, is one of the takeaways from a trove of putative early sketches of what became the Twitter logo. The images, uncovered by Slate, appear to be scrawled on brown paper towels you'd find in a bathroom. Twitter's design team also appears to have posted the illustrations on Dribbble. Twitter reps could not be reached for comment.
Assuming the images are on the level, it's appears the team threw out all kinds of ideas for the logo no matter how whimsical. Among the sketches, for instances, is a smoking bird and one that looks like he's wearing a wig. However some of the designs look like the image Twitter ultimately settled on.
