Sirocco the celebrity kākāpō has been found after losing his transmitter and disappearing two years ago.

"BOOM! Guess who's back..." his Facebook page states - along with a graphic photo of Sirocco caught in the act again.

It seems the cheeky kākāpō hasn't lost his taste for mounting men's heads. The image shows Sirocco frantically thrusting his wings as he dominates the cameraman, who visibly winces as he is taken by the large bird.

The frisky kākāpō first shot to fame in 2009 after enthusiastically attempting to mate with Stephen Fry's cameraman on a documentary shoot.

The video along with Mr Fry's commentary saying, "Sorry, but this is one of the funniest things I've ever seen. You are being shagged by a rare parrot," went viral.
