摘要：

Chemical analysis of rodenticide residues in regurgitated owl pellets has been shown to be a sensitive, non-invasive method for monitoring the potential exposure of Barn Owls to second-generation rodenticides in their prey. The method, originally developed for flocoumafen, has been extended to two other rodenticides, brodifacoum and difenacoum. The method was validated as part of a toxicity study in which Barn Owls were separately fed 40-130 mug day-1 of brodifacoum, difenacoum and flocoumafen in mice over 15 days. Each day an average of 25% of the consumed rodenticide was regurgitated in the pellets.
