I learned something really interesting about emus. They have two sets of eyelids, one for blinking and the other for keeping the dust out! London Zoo series
@cocokinetic I just read this on Google - Emus and ostriches both belong to the same family of birds, the ratite. They are similar in appearance and share genetic traits. Emus are native to Australia, while ostriches are native to Africa
So there is a connection; thanks for the most interesting info, Renee.
