Gecko commotion!

Two gecko's are either fighting, playing or mating outside my window - hmm, can't tell. There's plenty of commotion and a cacophony of gecko-squeaks. Oh wait! - I can see one has got hold of the other's tail with it's jaws. Whoa! - the gecko binary system has just swung haphazardly, pivoted on the hind legs of the biter, coming close to dropping off the window altogether. Nope - I still don't know what to make of it.
