כִּֽי־תַעֲזֹ֣ב לָאָ֣רֶץ בֵּצֶ֑יהָ וְֽעַל־עָפָ֥ר תְּחַמֵּֽם׃
El cual desampara en la tierra sus huevos, Y sobre el polvo los calienta,
Rashi on Job
For she leaves her eggs on the ground and she goes and warms herself on the dust at a distance.
Malbim on Job
Storks can fly and nest high-up, safe from predators; ostriches cannot.
