Mountain lions are making American roads safer by frightening away deer.

Mountain lions are making American roads safer by frightening away deer. On Washington’s Olympic Peninsula, where cougars were most active, deer-vehicle collisions fell 76%. A cougar eats about 48 deer a year, nowhere near enough to account for it, so researchers have concluded that the deer are avoiding the places cats hunt. Deer kill up to 440 Americans a year; cougars have killed 29 Americans since 1868. https://news.mongabay.com/2026/08/cougars-cut-deadly-vehicle-deer-collisions-in-the-u-s-by-up-to-76-study-shows/

#ShareGoodNewsToo@adapalmer I bet mountain lions are embarrassed that on net they reduce deer mortality.

Er, deer don't kill Americans, Americans don't drive carefully enough -

#ShareGoodNewsToo@adapalmer Deer kill Americans? Deer-vehicle collisions? That's quite a take.
Bloody deer, going and killing hundreds of people by... walking around.

I was thinking that too. Vehicular collisions with deer kill the 440. The deer are just doing their best to get from A to B.

Also wonder if wildlife overpasses and tunnels would help with cougars and deer.
