- Als Bettelverhalten oder kurz Betteln bezeichnet man in der Verhaltensbiologie ein Verhalten, durch das ein Sozialpartner (häufig ein Elternteil) zur Übergabe eines Objektes bewegt werden soll, in der Regel handelt es sich hierbei um Nahrung oder Wasser. Obwohl Bettelverhalten vor allem bei Jungtieren beobachtet wird, kann es auch bei erwachsenen Tieren auftreten, so betteln bsp. ausgewachsene Schimpansen und andere Primaten ihre Artgenossen um Futter an.

- Begging in animals is when an animal solicits being given resources by another animal. This is usually a young animal soliciting food from their parents, brood hosts or other adults. However, the resource is sometimes non-food related or may be solicited by adult animals. Begging behavior is most widely studied in birds, however, mammals, amphibians, and invertebrates perform begging displays. Generally in food solicitation, begging behavior is instinctive, although in some instances it is learned (e.g. pet cats and dogs). While the ultimate causation for begging is an increase in the animal's individual fitness, several theories have been proposed for how food begging evolved proximate causes including scramble competition, honest signalling of need, and cooperative begging by siblings. Various types of information such as nutritional status or immunocompetence can be transmitted with auditory and visual begging signals and the behavior can be modulated by several factors such as brood size and hormones. Similarly, several costs of begging have been investigated including energetic, growth and predation cost. Begging from humans also occurs under artificial circumstances such as donkeys, elephants and dolphins begging for food from tourists. (en)
