Pesticide residues in Arizona peregrine falcon eggs and prey

Organochlorine pesticides have been implicated in the decline of the peregrine falcon in North America. The eggshell thickness, fledging success, and contaminant levels for both prey and eggs are reported for peregrine falcon populations in Arizona during the period extending from 1978 to 1985. Fled...

Description
Summary:Organochlorine pesticides have been implicated in the decline of the peregrine falcon in North America. The eggshell thickness, fledging success, and contaminant levels for both prey and eggs are reported for peregrine falcon populations in Arizona during the period extending from 1978 to 1985. Fledging success was found to be 2.1 young/attempt which is twice the value necessary to maintain the population. Eggshell thinning was not sufficient to effect productivity. Although fifteen organochlorine pesticides were monitored, only DDE was detected at levels that are considered to be biologically significant. Several potential sources of DDE contamination are proposed.
