Abstract

Nine brown-headed cowbirds (Molothrus ater) were exposed to turf srayed with either EarthCare? (25% diazinon; 477 L a.i./ha) or Ortho-Klor? (12 .6% chlorpyrifos; 5.21 L a.i./ha.). Birds were euthanized and one foot from each bird was weathered outdoors for up to 28 days and the other foot was kept frozen until residue analysis. When compared to the unweathered feet, feet weathered for 28 days retained 43% and 37% of the diazinon and chlorpyrifors, respectively. Insecticide residues were below the level of detection (1.0 ppm) on control feet. Weathered feet may be used for determining organophosphorus insecticide exposure to birds.
