A day-old elk calf rests on a rocky slope above the Madison River. My favorite time to be in Yellowstone is from mid-May to mid-June when almost all species give birth.
A mother leopard rests in a tree while her cub sits on the ground below her. If you look closely, you will see she has at least three engorged ticks on her face. Her cub has at least one on its face as well.
