Organophosphate poisoning of Hyacinth Macaws in the Southern Pantanal, Brazil

Abstract 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...

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.
