J.L. Lincer David M. Bird Reed Bowen Stanley N. Wiemeyer 1987 Various species of kestrels have become important bioindicators of environmental quality and test species for comparative toxicology in captivity. At least 7 species of kestrels have been used to document the presence of environmental contamination primarily organochlorines and metals, in at least 15 countries. Captive kestrels have been used in studies involving a wide variety of environmental contaminants and toxicants examining: bioaccumulation; lethal toxicity using acute, chronic, and secondary exposures; effects on reproduction, eggshell thickness, and related enzyme systems; and effects on a wide variety of physiological and biochemical parameters. Field studies have examined the response of kestrels to exposure to insecticides. Kestrels should continue to play a vital role as a bioindicator and raptorial 'white mouse', especially because of their relationship to other falconiformes, several of which have been shown to be extremely sensitive to environmental changes. application/pdf en Raptor Research Foundation, Inc. and MacDonald Raptor Research Centre of McGill University The use of kestrels in toxicology chapter
