Wolves Apparently Regurgitate Berries To Feed Their Young, Study Finds

For the well read, wolves are known for snacking on blueberries. As it turns out, a good number of it doesn’t stay on their stomach to satisfy their hunger since a new research revealed that they regurgitate some of it to feed their pups.

Pup Diet

This is all thanks to a new observation made of an adult wolf regurgitating some of the berries it ate in order to feed its young. Per the researchers, this is the first that anyone ever documented the behavior, let alone find out that wolves are capable of doing it.

And because they’re carnivores that hunt in packs, it can be quite easy to imagine them filling their diet with deer and moose meat. However, an increasing number of emerging research are continuing to provide evidence that wolves don’t just have a taste for large, hoofed ungulates, but also eat fish and fruit, making their diet more varied than what is initially thought of.

For example, back in 2017, biologist Austin Homkes of Northern Michigan University in Marquette was able to track signals from a GPS collar worn by a wolf just near Minnesota’s Voyageurs National Park.  At the time Homkes was studying dietary and predatory habits and thought that the wolf was going to a spot where it stored its kill. Turns out, it was a spot where adult wolves brought food for their pups that were already out of the den. From there, other adult wolves started showing up and vomiting, with the pups eating up what fell on the ground. After going near, Homkes then found that they were partially chewed blueberries. His findings along with help from his colleagues were then published Tuesday in the Wildlife Society Bulletin.

Until the observation, scientists believed that pups merely ate blueberries while hanging around sites where adult wolves would meet after hunting for food.

“Such observations should be especially important for wildlife managers, who often focus only on wolf-ungulate interactions, forgetting about other food items consumed by wolves,” Robert Mysłajek, conservation biologist at the University of Warsaw, said.
