Behavior
The behavior of Marco Polo sheep is similar to other members of the Ovis genus. Marco Polo sheep generally live in small flocks of a few dozen. During the summer, they break into smaller flocks of the same sex. During and after the rut, however, they group together to form larger groups for protection, and to conserve energy.
When the rut begins, rams begin to fight for dominance among their flocks; dominant rams then choose their ewes without competition from the losers. Only mature rams (those over 6 years old) fight for dominance, the young will sometimes threaten older males, but never charge them. The mature rams fight by standing next to each other and spinning around, then one steps back and charges. O. a. polii males have been noted to rise up on their hind legs when they clash with opponents, which is not common in lowland sheep and similar to the fighting habits of goats. The males commonly emit grunts while fighting and often chip their horns or break their noses.
After dominance has been established, the rams begin to select their ewes. Although Marco Polo sheep rams are known to herd females, during the rut males pair off with females to reproduce. Males will approach a flock of females and smell the urine of possible mates. When smelling the ewe's urine, the males display the Flehmen response to test if the ewe is in estrus. Shackleton calls this phenomenon "lip-curl" and describes it as "...raising the head with the mouth open and upper lip curled back." The ram then splits from the flock to copulate with his ewe and afterward, will often stay with the flock for a month or two.

Famous quotes containing the word behavior:
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
“Our first line of defense in raising children with values is modeling good behavior ourselves. This is critical. How will our kids learn tolerance for others if our hearts are filled with hate? Learn compassion if we are indifferent? Perceive academics as important if soccer practice is a higher priority than homework?”
—Fred G. Gosman (20th century)
“Reading about ethics is about as likely to improve one’s behavior as reading about sports is to make one into an athlete.”
—Mason Cooley (b. 1927)
