This is a compilation of clips from a trail-cam in Yellowstone National Park of wolf parents bringing “toys” back to the den after a hunt to calm their anxious pups. Usually in the form of bones and antlers, but also the occasional tree branch. Some more details about the behavior while I get frustrated nobody ever brings me toys when I’m anxious:

Pups await food deliveries from successful hunts, but in the absence of food adults bring “toys.” The instinct to bring items back to the den may be reinforced by evolution, and probably helps keep adults from being mobbed by sharp puppy teeth.

Man, there were a lot of bones in that video. So, if you were wondering if you’ve been burying the bodies too shallow, the answer is yes, and I’m on to you.
