The common hill myna, a common pet, is well known for its talking ability and its relative, the common starling, is also adept at mimicry. [1]
Many animals make "food calls" to attract a mate, offspring, or other members of a social group to a food source. Perhaps the most elaborate food-related signal is the Waggle dance of honeybees studied by Karl von Frisch. One well-known example of begging of offspring in a clutch or litter is altricial songbirds. Young ravens will signal to ...
