It seems as if touch doesn’t merely increase your good feelings, but it also decreases your bad feelings.
For many years, researchers believed that the nerves of our skin could recognize just four kinds of stimulation: touch, heat, pain and itch. But there is growing evidence that cutaneous senses include another one that conveys information not just about touch, but about the pleasant properties of touch.
Animals that are social by nature, such as many birds and mammals, have areas that can’t be reached by their own design and must be addressed either by rubbing against objects or by grooming by others. These areas — largely the head and neck — appear to be endowed with extra nerves that feel good when stimulated.
I believe that all animals have moods. Sy Montgomery writes “hormones and neurotransmitters, the chemicals associated with human desire, fear, love, joy, and sadness, are highly conserved across taxa… This means that whether you’re a person or a monkey, a bird or a turtle, an octopus or a clam, the physiological changes that accompany our deepest-felt emotions (moods) appear to be the same. Even a brainless scallop’s little heart beats faster when the mollusk is approached by a predator, just like yours or mine would do were we to be accosted by a mugger.”
Wild animals that live in groups — herds, flocks, schools — form friendships. They derive benefit from being together. They don’t relish separation from their extended family.
A band is a family group of one adult stallion, one to three mares, and their foals. A herd can consist of multiple bands, and the connections between bands are weaker than within them, so a herd may show “fission-fusion” as it splits off a band or adds a band. In this book, the distinction does not matter, and I typically use “herd” to refer to a group of horses.
Horses are weird. Horses are unique among ungulates (large hoofed mammals such as rhinos, cattle, pigs, giraffes, camels, deer, and hippopotamus) and even most mammals in building and maintaining long-term bonds. Mares, stallions, and geldings all bond this way, choose to live together, and remain together until separated by fate. Horses have a sophisticated parental care system in which moms, dads, siblings, the peer group and others may play a role in raising foals of both sexes. A band of horses is a matriarchy, with one mare at the top and most of her daughters, regardless of age, and any sons that are below the age of 2. In the wild, feral bands of horses may have one or two stallions with the group, who play a role in defending territory, driving off other stallions, and fathering some darling foals. Herds form from bands, and alliances in the herd transcend family. In both herd and band, all cooperate in various responsibilities, such as predator defense.
One of the most common social behaviors is allogrooming (also known as mutual grooming). It is expressed by the lateral parallel body position of two horses that allows for nibbling along the back or withers of each horse. While this behavior can be considered grooming, it is also thought to facilitate pair-bonding and dominance structure between band mates
