This study aimed to analyze the chain and dynamics of the trade of wild birds between keepers and traders in an area of northeast Brazil. Profit from the purchase and sale of these animals in the trade chain was also estimated. The information was obtained through interviews with direct participants in the wild bird trade chain. We recorded a total of 34 bird species involved in illegal trade. In general, the purchase and sale values of songbirds are associated with the attractiveness and songs of the birds. Regarding the commercial potential of the species, those with high numbers of traded individuals had higher average purchase values and, especially, sale values. Birds with lower purchase values showed higher sale profits and were sold in large numbers. The purchase and sale values of songbirds in the present study show a significant economic return for those involved in this activity. The results of this study may provide data to support future studies on the conservation of wild birds, assisting in monitoring illegal trade, a persistent problem in the region studied.

鸣鸟的非法贸易：巴西东北部地区的活动分析

这项研究旨在分析巴西东北部某地区饲养者和贸易商之间野禽贸易的链式和动态。还估计了在贸易链中购买和出售这些动物的利润。这些信息是通过与野生鸟类贸易链中直接参与者的访谈获得的。我们记录了总共34种涉及非法贸易的鸟类。通常，鸣禽的购买和销售价值与鸣禽的吸引力和歌曲有关。关于该物种的商业潜力，那些拥有大量交易个体的物种具有更高的平均购买价值，尤其是销售价值。购买价值较低的鸟类显示出更高的销售利润，并且被大量出售。在本研究中，鸣禽的购买和销售价值为参与此活动的人们带来了可观的经济回报。这项研究的结果可能会提供数据，以支持将来有关野生鸟类保护的研究，协助监测非法贸易，这是该地区一个长期存在的问题。
