We know that Harpagornis preyed on moas because moa skeletons have been found with holes stabbed through their pelvic bones that exactly match the grasp of the eagles' claws.
Me teame, et harpagornis jahtis moasid, sest on leitud moa luustikke, mille vaagnaluudel on augud ja nende mõõdud klapivad kotka küünistega.
