Which geographical description fits the distribution of *H. nasicus* across North America?
Answer
Southern Canada down through the central and western United States and into Mexico.
The Western Hognose Snake exhibits a vast geographic distribution, demonstrating successful adaptation across diverse North American environments. Its range begins in the southern regions of Canada and extends southward across the central and western United States. Furthermore, its distribution continues into Mexico. This extensive spread covers various habitats, including dry scrublands, prairies, and bottomlands, leading to observable clinal variation or subspecies differentiation driven by localized environmental pressures across this large area.
