Twitter has just released a brand new bird icon which represents their brand.
The company said:
Our new bird grows out of love for ornithology, design within creative constraints, and simple geometry. This bird is crafted purely from three sets of overlapping circles — similar to how your networks, interests and ideas connect and intersect with peers and friends. Whether soaring high above the earth to take in a broad view, or flocking with other birds to achieve a common purpose, a bird in flight is the ultimate representation of freedom, hope and limitless possibility.
Twitter said that this bird would now be recognized as a universal symbol for their platform. They have updated their widgets and other resources with the new bird icon. Twitter is advising all third party developers to update their own products as well.
