Are prairie voles monogamous?
Prairie voles (Microtus ochrogaster) have long been of interest to neuroscientists and endocrinologists who study the social behaviour of animals, in part because this species forms monogamous pair bonds, essentially mating for life.
Are all voles monogamous?
Most notable, voles—unlike 97 percent of mammals—are monogamous, forming bonds that last long after mating (often for life, albeit a short one). “Male and female come together, male courts the female so that she goes into estrus, and they mate,” Young explains.
Are montane voles monogamous?

Why do voles fall in love?
They did not allow the animals to mate, but gave the female a dose of oxytocin and the male a dose of vasopressin.

How can you tell if a vole is male or female?
Carefully move the mouse’s tail out of the way so you can see its genital area. If the mouse’s genitals are about 1/4 of an inch away from its anus, the mouse is probably a female. If the genitals are much farther away from the anus, or you can see descended testicles, the mouse is a male.

Are voles social?
Both prairie voles and mice are social, but they exhibit important differences in the specificity and extent of their social behavior. While mice are often used to study social approach and other behaviors, voles are a more suitable species for the study of selective social relationships.
