Have you noticed any change on the micro-blogging site Twitter? Probably you might have missed it out since it is not a major revamp, but significant.

The Twitter bird has got a new avatar. The bird, which has been a trademark symbol of Twitter over the years, has undergone a simple makeover and it came into existence on Wednesday.

"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," said the Twitter's official blog post.

The new Twitter bird has better feathers and gesture compared to its former look. It will also replace the typical lowercase "t" of the site. The first letter of the company name in lowercase, used to represent the service of the Twitter on the various sharing buttons across the online. However, the new bird is taking over the place of "t" from now on.

The flying-high gesture of the new Twitter bird is touted as a symbolic representation of surging popularity and revenue of the micro-blogging site on the cyberspace.

The Twitter has managed to create more revenue through running the advertisements on the mobile space than desktop, said CEO Dick Costolo.

 "Twitter has generated more advertising revenue from its mobile platform than from its website on many days in the last quarter," Reuters quoted Costolo, who was speaking at a conference hosted by The Economist Group in San Francisco.   

Twitter started running the ads on its mobile platform from February, this year.

Costolo's remarks came in the backdrop of the other social networking website Facebook, facing a stiff challenge in pulling revenue from ads owing to the growing mobile audience. Facebook runs limited ads on its mobile page.

Meanwhile, to counter the problem in putting up the advertisements on the mobile version, Facebook went live with ads on the mobile platform in a bid to expand revenue prospects through increased marketing to smartphone users.
