Lion, Nairobi National Park, KenyaSometimes it can be tricky to distinguish a young male lion from a female. This lion clearly had what looked like the beginning growth of a mane, but sure enough it turned out to be a female. Certain older subadult and dominant females can have slight scruff on the jawline. She was the first lion we saw on our June of 2023 trip — day one in Nairobi National Park. Nikon Z8 with Nikkor 24-70mm lens (at 70mm) ISO 560, f/5.6 at 1/500th of a second.
