Pair Bonding
The prairie vole is special for having pair bonding with its partner. The male prairie vole has a continuous contact with its female, which lasts for all of their lives. If the female prairie vole dies, the male does not look for a new partner. Moreover, this constant relationship is more social than sexual. For this pair bonding to take place, the male must stay one day with the female after they breed. Other species, such as the montane vole, do not show this pair bonding behavior.

Famous quotes containing the words pair and/or bonding:
“We saw a pair of moose-horns on the shore, and I asked Joe if a moose had shed them; but he said there was a head attached to them, and I knew that they did not shed their heads more than once in their lives.”
—Henry David Thoreau (1817–1862)
“Attachment to a baby is a long-term process, not a single, magical moment. The opportunity for bonding at birth may be compared to falling in love—staying in love takes longer and demands more work.”
—T. Berry Brazelton (20th century)
