Non sono note informazioni specifiche sull'alimentazione dello struzzo d'Arabia, ma facendo riferimento allo struzzo comune, si nutriva principalmente di sostanze vegetali come semi, frutti ed erbe varie, e, raramente, di insetti.<ref>{{Britannica|ostrich|Struthio camelus|7 giugno 2023}}</ref>

L'etnografo svizzero [[Johann Ludwig Burckhardt|Jean Louis Burckhardt]] nelle ''Notes on the Bedouins and Wahábys'' (1830) fornì invece delle informazioni specifiche su alcuni comportamenti dello struzzo d'Arabia. La femmina deponeva in inverno tra dodici e ventuno uova, che venivano [[Cova delle uova|covate]] da lei e dal maschio, fino alla schiusa che si verificava in primavera. Il [[nido]], in parte interrato, veniva realizzato ai piedi di una collinetta, dalla quale uno dei genitori perlustrava le aree circostanti in cerca di pericoli.<ref name="Burckhardt" group=N>{{cita libro |titolo=Notes on the Bedouins and Wahábys |nome=Johann Ludwig |cognome=Burckhardt |wkautore=Johann Ludwig Burckhardt |anno=1830 |città=Londra |editore=Henry Colburn e Richard Bentley |url=https://books.google.it/books?id=sDZAAAAAYAAJ&newbks=1&newbks_redir=0&hl=it&source=gbs_navlinks_s |pp=123-124 |lingua=en |citazione=This bird breeds in the middle of winter, and lays from twelve to one-and-twenty eggs. The nest is generally made at the foot of some isolated hill. THe eggs are placed close together in a circle, half buried in sand, to protect them from rain, and a narrow trench is drawn around, whereby the water runs off. At ten or twelve feet from this circle, the female places two or three other eggs, which she does not hatch, but leaves for the young ones to feed upon immediately after they are hatched. The parent birds sit on the eggs in turn; and while one is so employed, the other stands keeping watch on the summit of the adjacent hill, which circumstance enables the Arabs to kill them. When they descry an ostrich standing in this manner on a hill, they conclude that some eggs must be near; the nest is soon found, and the ostriches fly away. The Arab then digs a hole in the ground near the eggs, puts his loaded gun into it, having fastenend to the lock a long burning match, the gun being pointed towards the eggs; he covers it with stones, and retires. Towards evening the ostriches return, and not perceiving any enemy, resume their places, generally both at once, upon the eggs: the gun, in due time, is discharged; and Arab finds, next morning, one of the ostriches, or frequently both, killed upon the spot. Such is the usual method of killing these birds, for the hunting of them is not practised in the NotrthenNorthen Arabian Desert.}}</ref>
