The ducklings would follow after whichever set best resembled their original imprint. After the ducklings showed a tendency towards one of the sets, the researchers put the ducklings in a different enclosure with different matching and non-matching pairs. They put ducklings in an enclosure and trailed two different pairs of objects around on strings, one pair of matching shapes (like two spheres) and one pair of non-matching shapes (like a cylinder and a cube). Ducklings are known to imprint on their mothers, but how much does this reveal about their cognitive abilities? To find out, scientists at the University of Oxford studied how the ducklings managed to differentiate between imprinted beings and non-imprinted. ![]()
