Although wolves use varied vocalizations to express themselves, their howl is the most famous. Howling helps keep family members (or pack-mates) together.
Wolves can howl to locate other wolves, advertise the size of their pack or territory, to warn other family members of danger using a bark howl, and more.
But do wolves ever just sing to make music, as we do?
“One of the most intriguing elements of wolf howling is what scientists call social glue. This spreading of good feeling like humans singing around a campfire, feeling closer to one another—it’s that same idea: you howl or harmonize and so reaffirm your social bonds with one another. That’s not surprising. Any pack animal really depends upon the others to survive.”
