These results show that the metabolic water mechanism is not able to sustain water loss independently and that food intake, specifically of plants with a high water content such as Euphorbia heterochroma, is necessary to overcome water loss challenges in the common ostrich's arid habitat. [80] The temperature of their beak, neck surfaces, lower legs, feet, and toes are regulated through heat exchange with the environment. Its speculated that early kiwis possibly could fly, explaining why they became so distant in location from their much larger relatives. Ostriches live in desert and savanna areas.
