Pepperberg (The Alex studies: cognitive and communicative abilities of gray parrots. Harvard University Press, Cambridge;1999) showed that some of the complex cognitive capabilities found in primates are also present in psittacine birds. Through the replication of an experiment performed with cotton-top tamarins (Saguinus oedipus oedipus) by Hauser et al. (Anim Behav 57:565-582; 1999), we examined a blue-fronted parrot's (Amazona aestiva) ability to generalize the solution of a particular problem in new but similar cases. Our results show that, at least when it comes to solving this particular problem, our parrot subject exhibited learning generalization capabilities resembling the tamarins'.
佩珀伯格（《亚历克斯的研究：灰鹦鹉的认知与交流能力》。哈佛大学出版社，剑桥；1999年）表明，灵长类动物所具备的一些复杂认知能力在鹦鹉科鸟类中也存在。通过重复豪泽等人（《动物行为》57:565 - 582；1999年）对棉顶狨猴（白领伶猴指名亚种）所做的一项实验，我们研究了一只蓝额亚马逊鹦鹉（蓝喉亚马逊鹦鹉）在新的但类似的情境中对特定问题解决方案进行归纳的能力。我们的结果表明，至少在解决这个特定问题时，我们的鹦鹉受试者展现出了与狨猴相似的学习归纳能力。
