The term 'Ostrich Lookalike' refers to three large flightless birds, the MOA, EMU, and RHEA. The MOA is a species of extinct bird native to New Zealand, with the scientific name Dinornis novaezelandiae. The EMU is a large bird native to Australia, with the scientific name Dromaius novaehollandiae. The RHEA is a large bird native to South America, with the scientific name RHEA americana. All three of these birds are similar in size and shape to the Ostrich, and are therefore referred to as Ostrich lookalikes.
