Thanks to commenter “B L”, who came into the comment section and wanted to bring Ostriches (and Kiwis) into the discussion! Ostriches are large flightless birds that can run really fast (43.5mph), are the heaviest birds, and lay the biggest eggs of any animal. Native ostriches can currently only be found in Africa (though there are feral herds in Australia), and although there are 13 species attributed to the ostrich family, there are currently only two living species. For our flightless feathered friends who flee fast, bury your head into these ostrich memes!
