"...you might be wondering if Emus are one of the few that can interbreed. Well, we’ve got an answer for you."
"...Emus are the only species in their genus and family. And this makes them genetically distinct from other animals by a great deal."
"There appears to be no record of Emu hybrids. So, it is unlikely that Emus can interbreed. Besides, the closest animals to Emus genetically are the Cassowaries."
"Emus are generally monogamous. They typically move around in tight breeding pairs for the most part of the year."
