Back cover “Featured Photo” by © P. Ross Gorman of Cody, Wyoming: Clark’s Nutcracker placing a salamander on its back in the middle of an active roadway, 22 April 2019, Yellowstone National Park, Wyoming. Note on both the salamander and the nutcracker the whitish droplets of toxin excreted by the salamander, suggesting that the salamander’s skin had already been pinched or pierced. But the salamander is otherwise intact and actively defending itself.
