The populations of hyacinth macaws (Anodorhynchus hyacinthinus), an emblematic species, have suffered declines due to many environmental factors. The Hyacinth Macaw Institute's actions are showing positive outcomes for the conservation of A. hyacinthinus. However, environmental issues, such as fires and deforestation due to inefficient and unsustainable cattle ranching practices, are a threat to the biodiversity. Another major threat is the reckless use of pesticides. The objective of this manuscript is to describe the findings, in the Pantanal, of three dead hyacinth macaws and to investigate their cause of death and conservation implications. A necropsy was conducted on two individuals and biological samples were collected and sent to conduct toxicological exams to test for organophosphates, organochlorines, and carbomates. Compatible with other findings, results showed a highly dangerous level of organophosphate, 158.44 ppb. We describe for the first time, a rare, isolated but unusual mortality event associated with organophosphate pesticide poisoning of hyacinth macaws. Mortality reports for bees and other bird species on how the improper use of pesticides can potentially cause the contamination of food and water resources are discussed. These factors are antagonistic to long-term efforts to preserve wildlife and carry out other conservation efforts in Brazil's southern Pantanal.
金刚鹦鹉（Anodorhynchus hyacinthinus）是一种具有象征意义的物种，由于许多环境因素，其数量已经减少。金刚鹦鹉研究所的行动表明，在保护 A. hyacinthinus 方面正在取得积极成果。然而，环境问题，如由于低效和不可持续的养牛业而导致的火灾和森林砍伐，对生物多样性构成了威胁。另一个主要威胁是农药的滥用。本文的目的是描述在潘塔纳尔发现的三只死亡的金刚鹦鹉的发现结果，并调查其死因和保护意义。对其中两人进行了尸检，并收集了生物样本进行毒理学检查，以检测有机磷、有机氯和氨基甲酸酯。与其他发现结果一致，结果显示出高度危险的有机磷水平，为 158.44ppb。我们首次描述了与金刚鹦鹉有机磷农药中毒有关的罕见、孤立但不寻常的死亡事件。讨论了蜜蜂和其他鸟类物种的死亡报告，说明不当使用农药可能会导致食物和水资源受到污染。这些因素与巴西南部潘塔纳尔地区保护野生动物和开展其他保护工作的长期努力背道而驰。
