Habitat and feeding
Giraffes usually inhabit savannas, grasslands and open woodlands. They prefer Acacia, Commiphora, Combretum and open Terminalia woodlands over denser environments like Brachystegia woodlands.[8]:322 The Angolan giraffe can be found in desert environments.[53] Giraffes browse on the twigs of trees, preferring trees of genera Acacia, Commiphora and Terminalia,[4] which are important sources of calcium and protein to sustain the giraffe's growth rate.[9] They also feed on shrubs, grass and fruit.[8]:324 A giraffe eats around 34 kg (75 lb) of foliage daily.[24] When stressed, giraffes may chew the bark off branches. Although herbivorous, the giraffe has been known to visit carcasses and lick dried meat off bones.[8]:325
During the wet season, food is abundant and giraffes are more spread out, while during the dry season, they gather around the remaining evergreen trees and bushes.[4] Mothers tend to feed in open areas, presumably to make it easier to detect predators, although this may reduce their feeding efficiency.[43] As a ruminant, the giraffe first chews its food, then swallows it for processing and then visibly passes the half-digested cud up the neck and back into the mouth to chew again.[27]:78–79 It is common for a giraffe to salivate while feeding.[28]:27 The giraffe requires less food than many other herbivores, because the foliage it eats has more concentrated nutrients and it has a more efficient digestive system.[4] The animal's feces come in the form of small pellets.[12] When it has access to water, a giraffe drinks at intervals no longer than three days.[24]
Giraffes have a great effect on the trees that they feed on, delaying the growth of young trees for some years and giving "waistlines" to trees that are too tall.[24] Feeding is at its highest during the first and last hours of daytime. Between these hours, giraffes mostly stand and ruminate. Rumination is the dominant activity during the night, when it is mostly done lying down
