The popular micro blogging service Twitter has given its logo a makeover. The new silhouette of the little blue bird now looks happier and chirpier than before.

There won't be any text, lowercase "t" or bubbled typefaces with Twitter bird from now on. "Starting today you'll begin to notice a simplified Twitter bird. From now on, this bird will be the universally recognisable symbol of Twitter. (Twitter is the bird, the bird is Twitter.) There's no longer a need for text, bubbled typefaces, or a lowercase "t" to represent Twitter." That's what Twitter said in their recent blog post.

The bird is a little bit redesigned and Twitter is planning to bring uniformity to the symbol. Twitter is known for their little blue bird logo over the past six years. This new logo is created using three overlapping circles that represents users' ideas, networks and interests connecting with others. The new logo looks quite similar to the old one but is a little bit slimmer. And it's also symbolic.

"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," Doug Bowman, creative director at Twitter, said. It represents Twitter's love for ornithology and how people use this micro blogging service.

"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," added Bowman.

Twitter also released a new introductory video titled as "Our New Twitter Bird". People can find updated guidelines and information about this new logo in Twitter's brand resources page.
