female. The elides show the male reaching toward and manipulating the female's 
genitals, hiring this same episode oral contacts and Incomplete mountings 
were nlso common. In spite of the persistence of her mate, the female twice 
fled from him, but was overtaken before she had joined the male from the 
neighboring group. On this and other occasions I have seen the male restrain

next slide. 
Although it Is possible that the female may remain with the neighboring 
male, ehe probably does not. An episode that I observed recently perhaps 
best illustrates the typical situation. A male and female of neighboring 
pairs approached each other, copulated, then separated, the male moving off 
while the female returned to her customary partner. Although her mate had 
twice ruehed the pair ns they attempted to copulate, he showed no unusual 
reaction to the female upon her return. 
There are many other indications that in spite of the sexual attraction 
of both male and female to members of neighboring groups, the bond between 
mates ia strong and enduring. Although I cannot identify most animals 
individually, in those pairs in Which I can there has been no evidence of a 
change since my first contacts. Ordinarily the members of a pair follow 
each other cloaelj and are usually found within a few feet of each other 
during feeding and rest periods. Generally speaking, the attraction is mutual.
