In this photo provided by Briana Abrahms, a female cheetah and her cub sit watchfully in front of a herd of zebra in northern Botswana on Aug. 23, 2011. The female wears a GPS collar as part of a study. Cheetahs are usually daytime hunters, but the speedy big cats will shift their activity toward dawn and dusk hours during warmer weather, according to a study published Wednesday, Nov. 8, 2023, in the journal Proceedings of the Royal Society B. Unfortunately for endangered cheetahs, that sets them up for more potential conflicts with mostly nocturnal competing predators like lions and leopards, say the authors of the paper.
