ANTICOAGULANT RODENTICIDES16. Non-target animals are occasionally casualties of poisoning caused by wilful oraccidental non-compliance with good practice in rodenticide baiting. Indirect orsecondary poisoning can also occur when predators, scavengers or curiousanimals ingest rodents killed or affected by rodenticides. The WIIS Scotlandoffers a unique opportunity to probe wider environmental contamination bylooking for rodenticide residues present in non-target animals that otherwisewould not be available. Routine monitoring of liver tissue from wild mammals,birds of prey and other animals is carried out in order to assess the magnitudeand frequency of exposure to anticoagulant rodenticides. The results provide aneffective indication of the non-target animals exposed to anticoagulantrodenticides.In 2011, SASA Pesticides & Wildlife Branch tested 210 livers from a variety ofanimals for the presence of residues of anticoagulant rodenticides. Residueswere detected and identified in the livers of 87 specimens i.e. 41% of the totalnumber of livers tested (Table 6).Table 6: Species tested throughout 2011 for the presence of residues ofanticoagulant rodenticides aSpecies Number tested Number positive bBuzzard 50 21Eagle-golden 5 1Eagle-sea 5 3Goshawk 2 -Kestrel 4 1Merlin 1 -Peregrine falcon 4 2Red kite 14 9Sparrowhawk 15 7Barn Owl 2 1Long-eared Owl 1 -Short-eared Owl 1 -Tawny owl 9 4Crow 3 -Jackdaw 1 -Raven 4 -Rook 5 -Greenfinch 3 -Pigeon 1 -Chaffinch 1 -Capercaillie 1 -11
