Behaviour
Dorcas gazelles are highly adapted to the desert; they can go their entire lives without drinking, as they can get all of the moisture they need from the plants in their diets, though they do drink when water is available. They are able to withstand high temperatures, but when it is very hot, they are active mainly at dawn, dusk and during the night. In areas where they face human predation, they tend to be active only at night to minimise the risk of falling prey to hunters. These gazelles feed on leaves, flowers, and pods of many species of acacia trees, as well as the leaves, twigs and fruits of various bushes. They occasionally stand on their hind legs to browse from trees, and after rain, they have been observed digging out bulbs from the ground. Dorcas gazelles are able to run at speeds up to 80 km per hour (50 mph) to 96 km per hour (60 mph) when threatened, they tail-twitch and make bouncing leaps with their heads held high (stotting), possibly to announce they have seen a predator.

Famous quotes containing the word behaviour:
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
