Citrated plasma samples were sent to the University of Miami Avian and Wildlife Laboratory for clinical determination of total protein, plasma electrophoresis (pre-albumin, albumin, alpha 1 globulins, alpha 2 globulins, beta globulins, gamma globulins) and aspartate aminotransferase and creatine phosphokinase activities.

Range finding trial in which kestrels were fed diets containing varying quantities of brodifacoum and signs of intoxication were monitored.

Trial examining blood clotting function response in kestrels initially fed a diet containing chlorophacinone (CPN) or brodifacoum (BROD), and following a recovery period, kestrels were challenged with a diet containing chlorophacinone. Kestrels received two 25 ± 0.1 g NBP meatballs daily for a 7-day period containing either vehicle, 1.5 µg CPN/g wet wt diet (i.e., 1.5 ppm chlorophacinone) or 0.5 µg brodifacoum/g wet wt (i.e., 0.5 ppm brodifacoum) during an initial exposure phase. Following 7 day recovery period, these kestrels were then fed 0.75 µg CPN/g wet wt diet (i.e., 0.75 ppm chlorophacinone) for a 7 day challenge exposure phase. Hereafter, these groups are designated control-chlorophacinone challenge (CON-CPN), chlorophacinone-chlorophacinone challenge (CPN-CPN), and brodifacoum-chlorophacinone challenge (BROD-CPN).
