Wetland birds poisoned by endosulfan and chlorpyrifos in Argentina

摘要

A serious and highly visible mass bird kill occurred in Argentina in February 2012, linked to use of the insecticides endosulfan and chlorpyrifos. More than a hundred dead and dying Southern Screamer birds (Chauna torquata) were found around the edge of La Picasa lake, in Santa Fe province, to the north-west of Buenos Aires. The Southern Screamer is a large, goose-like bird that inhabits swamps and wetlands and feeds mainly on plant materials.
