Sting's form is rising nicely.  He has a varied song and his display can be quite eye-catching.  Unlike the earlier video that I posted on this blog, the video below only shows him displaying his tails by raising them high in the air, wagging them 4 or 5 times, and then slowly bringing them down. This display is different from his earlier song and display and I found it interesting.  His form continues to improve though he still does not react to females although he is 15 months old. I think he is maturing slowly and will only realise his full potential after his next moult.
