The Twitter bird has flown the coop.

The platform's logo has officially changed to a white "X" on a black background overnight, replacing the familiar blue bird symbol.

It's the latest change by new owner Elon Musk.

Greg Smith at Devon Funds Management told Mike Hosking everyone knew the change was coming.

He says tweets will now be called 'Xs' - but Musk is still thinking of what to call re-tweets.
