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 the 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.
