This paper presents results of almost 30 years of study of the cognitive and communicative activities of Grey parrots (Psittacus erithacus), conventionally regarded as mindless mimics. These studies have demonstrated that Grey parrots can solve various cognitive tasks and acquire and use English speech in ways that often resemble those of very young children. Examples include the concepts of same/different, colour, size and shape. The parrot Alex can also recognize and distinguish numbers up to six, and spontaneously demonstrated his ability to grasp the concept of ''none''. Given the evolutionary distance between birds and mammals, these results have intriguing implications for the evolution of intelligence, the study of comparative intelligence, and the care and maintenance of birds held in captivity in zoos and as companion animals.

该杂志发表有关驯养和利用动物行为的相关信息。涵盖的主题包括：-与动物管理和福利有关的农场、动物园和实验室动物的行为-与行为问题有关的伴侣动物的行为，例如，为不同目的而训练狗，与行为问题有关——当这些研究从应用角度相关时，对野生动物的行为进行研究，例如与野生动物管理、害虫管理或自然保护相关——相关领域内的方法学研究领域主要科目是农场动物、伴侣动物和实验室动物，当然也包括家禽。该杂志还涉及以下动物主题：-参与任何农业系统的动物，例如鹿、兔子和毛皮动物——任何形式的禁闭，例如。动物园、野生动物园和其他形式的展示——野生动物，以及任何影响农业经营的动物物种，例如作为损失或损坏的原因——在某些情况下，用于狩猎、娱乐等的物种也可以被视为可接受的对象——如果材料与它们的行为要求有关，则实验室动物

The journal "Applied Animal Behaviour Science" publishes research related to the domestication and utilization of animal behavior. Topics covered include: the behavior of farm, zoo, and laboratory animals in relation to animal management and welfare; behavioral issues in companion animals, such as training dogs for various purposes; and studies of wild animal behavior when relevant from an applied perspective, particularly in relation to wildlife management, pest control, or conservation. The primary subjects of research are farm animals, companion animals, and laboratory animals, including poultry. Additionally, the journal addresses the following animal topics: animals involved in any agricultural system, such as deer, rabbits, and fur-bearing animals; any form of confinement, such as zoos, wildlife parks, and other forms of display; and any animal species that impact agricultural operations, such as those causing loss or damage. In some cases, species used for hunting and recreation may also be considered acceptable subjects, provided that the materials relate to their behavioral requirements, including laboratory animals.
