research
Since 1985 the American ecologist Steve Beissinger has been researching the living conditions and behavior of animals in a colony of Green-rumped Sparrow Parrots in Venezuela. Among other things, this long-term study provided information on the ecological and evolutionary background of learning to imitate parrots: According to this, young parrots learn from their parents the typical basic patterns of intra-species communication, but vary these individually and can vary them throughout their life so that each animal has its 'own' Contact calls developed and can be individually recognized by every other conspecific.
