American Bittern again

A trip down Carlton Marshes on Saturday 14th April and I eventually saw the American Bittern emerging amongst the Juncus in the cleared area just east of the dye usual area, it stick its head and breast up and the snuck down and slunk amongst the Juncus and then into the reeds all for a magnificent 5 seconds. It showed a brown head a white super cilia and dark thick stripes down its breast. I shouted it out as I was the only one to see it but it did later emerge amongst the edge of the reeds slightly further east by the clear field.
