Abstract

Breeding bird density, species diversity, nesting success, brain cholinesterase activity, and presence of sick or dead birds were evaluated on control and treatment plots during the year of spraying and 1 yr after. No adverse effects were detected in the Dimilin plots, and no major effects in the Sevin-4-Oil plots, although 2 of 55 birds showed brain cholinesterase depression. In the Orthene plots, however, studies of brain cholinesterase activity showed severe and prolonged depression (commonly 30-50%) for up to at least 33 days. Abnormal behavior symptomatic of organophosphate poisoning was also observed.-from US Govt Reports Announcements, 24, 1981
