Fairy wren nestlings learn “passwords,” or unique single notes, from their mothers while still in their eggs; after birth they must use the passwords when calling for food, or the mothers will abandon the nest. In a 2012 study, scientists in Australia experimented with switching eggs and mothers, and found that passwords were not genetically inherited; the chicks assumed the passwords of their adopted mothers.
One must love people a good deal whom one takes pains to convince or instruct.
—Mary de la Riviere Manley, 1720
