Utah: Scientists reviewing video from camera traps watched dumbfounded as a seven kilogram badger worked four days to bury a 22-kilogram calf carcass.

Badgers, carnivores native to the American West, are generally nocturnal and spend most of their time in burrows.

They are known to cache food to eat later — squirrels and rabbits, typically. No one has ever seen a badger put away such a large hunk of meat.

Scientists at the University of Utah had put out seven calf carcasses in Utah's Grassy Mountains in January 2016 in an attempt to study scavenging behaviour.
