~ 150 cm long.

Found among rocks on the outer jogging trail. I waited a few minutes for the head to emerge, and while it was clearly alive (visibly breathing and moving its tail), the fact that it was moving very slowly forwards and backwards made it look like it was stuck. Not wanting to unduly stress the snake, I tried moving some of the stones near its midbody to give it more room to slide back out.

When its head finally popped into view after about 5 minutes, it looked very contorted - turns out it was regurgitating a toad which it had probably found among the stones. Either it couldn't extract the toad from the small crevice or it was stressed by the (naturally) forming crowd. Thankfully, once it regurgitated the toad, it rapidly slunk away into a hole.

Only the second time I've seen this species, and the first time I've managed to photograph it; unfortunate that it lost a meal.
