BINGO!
Thats exactly what it is...judging from that website and the pictures.. now to figure if it's sick or not.....it seems like the "bark sheding" seems normal but the green leaf droppings is what's concerning.
Bark is normal, kind of a neat thing. Pretty common tree . They get huge. Very desirable. I'd luv one in my yard but I haven't got any more room for anything else. Good luck and let inquiring minds know what is up if you find out.
