Résumé
The West African country of Niger is host to the last free-roaming herd of G. c. peralta (Giraffa camelopardalis peralta). This study examines the dietary preferences of these giraffes, with the goal of preserving the herd in the regions that they currently inhabit. The giraffes exhibit a sexual segregation in their dry-season habitat selection and forage choices. The females show a strong preference for the intermediate zone (IM) when with their newborns. The males and pregnant females show a preference for the Dallol Bosso (DB). Nursing cows avoid tannins and high human densities. Bulls and non-nursing cows prefer high protein and high fat forage, while sub-adults show a strong preference for high protein and carbohydrate contents and moderate tannin levels. Combretum glutinosum is the most preferred species for adults of both sexes in the IM. Adult females show the next strongest preference for Acacia senegal in the IM. Males and females have strong preferences for both Acacia nilotica and Acacia. seyal in the DB. Subadults of both sexes strongly prefer Prosopis. africana in the IM. Unlike females, males retain their preference for A. nilotica when in the IM.
