Otididae
Otididae sunt magnae aves terrestres ordinis Otidiformium quae plerumque in siccis terris gramineis et in tesquis Mundi Veteri habitant. Sunt a 40 ad 150 centimetra longi.

Mores et oecologia
Otididae sunt omnivora et indagatores occasionis, qui foliis, gemmis, seminibus, fructibus, invertebratis, parvisque  vertebratis vescuntur. Nidos in solo faciunt, unde ova et fetura saepe praedatoribus obeunt. Firme cruribus pollicibusque pedis ambulant, cibum temere vellicantes. Plurimae currere potius quam volare malunt. Femina a tribus ad quinque ova obscura et maculosa in lacuna in solo ponit, quae sola incubat.
