HOW THINGS WORKZ on Instagram: "Wolves' vocalizations can be separated into four categories: barking, whimpering, growling, and howling. Sounds created by the wolf may actually be a combination of sounds such as a bark-howl or growl-bark. Howling helps keep family members (or pack-mates) together. Because a pack's territory can range over vast areas, it's not unusual for members of the pack to become separated from one another. Wolves can call to one another over great distances by howling. #sno
