especially strikingly colored and also the zoological layman unmistakable baboons is the drill (Mandrillus leucophaeus) and the Mandrill (Mandrillus sphinx). The shortly hairy, only stub-good tail (5-8 cm) sticks out usually steeply high-put from that of bluish-red colored landscape of the buttocks-calluses, that enormous sizes often attain with the males. Females and young are equipped only with less colorful and less big seat-calluses.
Spread, habitat Both near relatives types live in the tropical forests in the southwest of Africa in the area of Cameroon approximately. Here they are mainly at the ground, where they pick up fallen fruits, stones, foliage and branches turn on the search of insects and smaller vertebrates.
Insignia You grotesquely working face-jewelry in form of colored, parallel pleated skin-parts over Knochenwülsten on both sides of the nose helped them also to the name "Cheek-furrow-baboon." Also the longitudinal-welts are colored black in the black face of the discipline on both sides of the nose and take off strongly through the white-haired Gesichtsumrahmung as impressive mask. In the Mandrillgesicht, one emptied a color-box seemingly: Beside the red nose shines on both sides of several bulge-y jewelry-welts in light blue, and the shining-yellow beard stands by it in virtually crying contrast. These bare skin-places still increase in colored-ness with arousal or fear and are at the service of the Signalgebung and face-gesture, d. h. the social communication.
The young of both types have light faces at first, that soon itself into the darkness until black of the adult umfärben, through what the aforementioned color-brands all the more clearly take off. The Nasenwülste are in the singular with the drill-baby, with the Mandrillkind however many times existing, so that one can distinguish the otherwise very similar boys well at this characteristic.
Shape Both types are heavily in the adult condition and powerful working animals of over 50 kg of weight and about 80 cm of seat-height. The females always are clearly smaller and easier than the males.
In the fur-coloring, drill and Mandrill essentially don't differ. The back-part with the drill is black-brownish until gloomily olivfarben, with the Mandrill gloomily dun with greenish glimmer, while the undersides are held with both in different gray-sounds. So it is no miracle that such a colorful drawing plays an important role in the social-behavior of the individuals.
Social-behavior This is applicable also to the buttocks-area, that is offered the Ranghöheren with the servility-gesture and should induce this to the Aufreiten. It already is indicated with it that this gesture comes from the sexual-area where the conception-ready female presents its then strongly swollen buttocks and sexual-calluses the mating-joyful male. This invitation-gesture was solved (ritualize) from the sexual area in the course of the tribal-history and won social position-function. So also fearful males present its sexual-region before the position-higher male today, and this rides "formally" on, so that the self-assessment is confirmed on the social position-leader and is fixed again and again with it. With sexuality, this often earlier than greed (or even "homosexuality") misinterpreted behavior has to do nothing more of course: It became pure appeasement-gesture, that reduces position-fights unnecessary innerartliche.
Enemy-behavior When threatening, the male extends both poor after above-outside, sinks in the head little and exposes the dagger-good cuspids in forceful gesture. Of course this serious fight-announcement doesn't have anything to do with the yawn although this gesture resembles the drowsy yawn purely formally and is misinterpreted by the inexperienced observer so. If this threatening doesn't yet impress the aggressor, the next step is switched on: On - and coming off and colored shining of even further shining color-stains at hands and feet as well as at the breast.
If the fight really occurs, so it reveals itself a gorilla equal strength and ferocity, that are connected with unbelievable speed of the actions. Drill and Mandrill don't let themselves intimidate so easily from any aggressor.
The lifespan of the Mandrills in captivity amounts to approximately 30 years.
Endangering Both drills and Mandrill are threatened in its habitat through Bejagung and habitat-destruction seriously.
