I know that the answer to the question "What did Aristotle write that Pliny also observed?" is in "Aristotle noted that cranes traveled from the steppes of Scythia to marshes at the headwaters of the Nile. Pliny the Elder, in his Historia Naturalis, repeats Aristotle's observations.". Can you tell me what it is?
