You shall not avenge, nor bear any grudge against the children of your people, but you shall love your neighbor as yourself…
Small birds have an intense natural antipathy of nocturnal birds of prey. If one of these birds happens to be seen out of its lurking-place during the day they assail it vigorously, resent its intrusion, and avenge the oppression exercised over them during the night by combined attacks. This antipathy has been taken advantage of for the purpose of catching birds ever since the days of Aristotle. The catcher imitates, for instance, the voice of an owl about an hour before sunset, when the birds will flock together and perch on the trees or bushes in the suspected neighbourhood. The twigs, &c., having been previously covered with bird-lime, the birds pay their liberty and perhaps life as the penalty of their desire to avenge themselves on the owl.
