During the night these Baboons hide together in holes in the 

 rocks, whence, on the return of the morning sun, they emerge 

 and sit warming themselves, before starting on their marauding 

 expeditions in the cultivated fields, or in the vegetation which 

 clothes the sides of the deep valleys, where they feed largely 

 on the leaves of the trees. Their disposition is, among them- 

 selves, harmless. As a rule two to six year old males lead with 

 grave strides a herd of twenty to thirty females and young, the 

 latter now playing with each other, and scampering about the 

 troop, now carried by their mothers, and sometimes pinched 

 and boxed on the ears by them. As soon as, but not before, 

 the leader has assured himself of any danger, he utters a gentle 

 bark, to which the whole troop responds and retreats back into 

 safety among the rocks. The old males then stand on their 

 hind-feet barking and displaying to the intruder their long white 

 teeth. On their marauding expeditions, or when in flight, they do 

 not usually exhibit great haste, the whole troop generally going 

 in single file with an old Sultan bringing up thd rear. Often 

 several troops mingle together during the day, but at nightfall 

 each returns to its own headquarters. 



Their cry is a sharp bark, but that of the old males is very 

 hoarse. One of their great enemies is the Lammergeier or 

 Bearded Vulture. 



These observations have been extracted from the account 

 given of this species by von Heuglin, who discovered it during 

 his Abyssinian expedition in 1853.
