Ha! I found a disposable camera with flash and 3 pix left! The flash scared the male off, the female squirmed around on the ground for a few seconds, then dragged her ass (literally!) into the shrubbery. They had been shrieking and chitterring quite loudly. The first time I went out, to within 10 ft of them, they stopped making noise, but not humping!
Picture to follow, hopefully.
