Short video description
Communication is especially important for animals, like wolves, that live together in family groups, where coordinating, cooperating, and reinforcing bonds and status are all part of a necessary daily routine. Within a family of wolves, communication helps maintain social stability. It helps to reinforce pack solidarity and enables the opportunity for young pack members to learn information specific to the pack and how to survive. As with any highly social animal, communication amongst wolves is particularly complex and involved and it is vital to keeping the family functioning together as one.

The Language of Wolves - Living with Wolves

Facial expressions have an important role in interpersonal communications and estimation of emotional states or intentions. Automatic recognition of facial expressions has led to many practical applications and became one of the important topics in computer vision. We present a facial expression recognition system that relies on geometry-based features extracted from eye and eyebrow regions of the face. The proposed system detects keypoints on frontal face images and forms a feature set using geometric relationships among groups of detected keypoints. Obtained feature set is refined and reduced using the sequential forward selection SFS algorithm and fed to a support vector machine classifier to recognize five facial expression classes.

The Language of Wolves

Foxes communicate with each other in a variety of ways. As in the domestic dog and many other carnivores, many different facial expressions and body postures are used. Friendly greetings such as tail wagging are used when meeting family members, and aggressive behaviour may be directed towards intruding neighbouring foxes.

Over the past few years and after the successful reintroduction of beavers in Scotland, there have been talks and interest about the possibility of lynx reintroduction in Scotland. Therefore we were all keen to know more about the lynx ecology, management and conflict mitigations Norway. Norway has four main carnivores with some habitat where all of them co-exist.
