Why Wolves Howl
Wolves have their own way of communicating: they howl. Scientists of the Messerli Research Institute at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) in collaboration with scientists of the Universities of Zürich and Parma have investigated what drives this form of vocalization. Wolves howl in order to communicate with pack members Credit: Walter Vorbeck When individual wolves are separated from the pack, the intensity of howling of each remaining pack member is determined by the relationship between the separated wolf and the howler, while emotional stress is less important. The results are published in the prestigious journal Current Biology.
