An evaluation of the acute oral toxicity of brodifacoum to birds


Single acute doses of the rodenticide brodifacoum were administered orally to 13 species of birds which are at risk from accidental poisoning during rabbit or possum control operations. Median lethal dose values from less than 1 to more than 20 mg/kg were obtained for some species. Gulls and Canada geese appear to be particularly susceptible. Several species, particularly the gulls, waxeyes, sparrows, mallard ducks and harrier hawks, seem to be vulnerable to lead poisoning.
