With spurs clanking and daggers at their waists, the gauchos smoked, drank, and ate whatever they could shoot. (Lond.) 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. Is a frog a reptile? The ostrich is an example of a ratite: a distantly related group of large flightless birds, including the kiwi, the emu, and the rhea. In reality, ostriches stick their heads in the ground to dig a shallow hole, where they can subsequently make their nests. They write new content and verify and edit content received from contributors.
