“…These compounds may therefore similarly pose a risk to other species at the same trophic level, such as insectivorous birds (Rammell et al, 1984;Empson and Miskelly, 1999;Robertson and Colbourne, 2001). The frequencies with which we detected SGAR residues by HPLC were towards the mid (brodifacoum, bromadiolone) or low (difenacoum) end of the spectrum documented for predatory birds and mammals in Britain (Table 1), but were comparable in some instances to prevalence rates in species considered to be specialist predators of small mammals, such as the polecat (Shore et al, 2003a), barn owl (Tyto alba) (Newton et al, 1999b) and tawny owl (Strix aluco) (Walker et al, 2008).…”

Article (refereed)Dowding (Singleton et al., 1999;Stenseth et al., 2003).72 Consequently, a range of methods is employed to reduce rodent density and 73 associated damage. This is most commonly done in developed countries using 74 anticoagulant rodenticides, vitamin K antagonists that prevent the synthesis of 75 functional prothombrin and related blood-clotting factors. Extensive use of first-76 generation anticoagulant rodenticides (FGARs) during the 1950s, however, led to the 77 evolution of genetic resistance in brown rats (Rattus norvegicus), with widespread 78 cross-resistance to other compounds (Cowan et al., 1995;Thijssen, 1995). As a 79 result, more potent second-generation anticoagulant rodenticides (SGARs) were 80 developed which have a greater affinity to binding sites, resulting in greater 81 accumulation, persistence and toxicity (Parmar et al., 1987; Huckle and Warburton, 82 1986). 83Given their mode of action, both FGARs and SGARs are potentially harmful to all 84 vertebrates, and so users are expected to adopt measures that limit direct exposure 85 to non-target species. However, the degree to which these preventive measures are 86 adhered to, particularly by non-professionals, is unknown. For example, in Britain 87 some products are readily available to householders who may be less aware of the 88 risks of non-target poisoning and/or less likely to follow manufacturer's guidelines.89 Non-target species may also be deliberately poisoned (Barnett et al., 2006). 90Most studies investigating indirect exposure of non-target species to 91 anticoagulant rodenticides have focussed on the consumption of poisoned rodents by 92 predatory birds and mammals (Newton et al

“…In addition to being more ecient for cat control, starting both control programs together would also result in advantages due to synergetic eects: costs may be reduced (if costs related to transportation, or hunting and trapping can be shared by the two programs) and eciency might be increased (e.g. through the additive eects of primary and secondary poisoning of predators, Rammel et al, 1984;Flux, 1993;Robertson et al, 1994).…”

Brodifacoum, an anticoagulant used in cereal-based baits for the control of vertebrate pests, especially rodents, may be accidentally ingested by non-target species. In birds, its acute toxicity varies from an LD 50 of < 1 mg/kg in pukeko to >20 mg/kg in paradise shelduck. Fourteen indigenous and eight introduced bird species have been reported killed by field use of brodifacoum in New Zealand. Populations of three species (western weka, Stewart Island weka, and pukeko) have been severely reduced in poisoned areas. There are no published data on the acute toxicity of brodifacoum in bats, reptiles, or amphibians. Invertebrates are unlikely to be killed by anticoagulants. Because of the high toxicity of brodifacoum, all vertebrates that eat baits or poisoned prey are at risk. Brodifacoum is only slowly eliminated from the liver, and therefore accumulates in vertebrates if there are repeated exposures to the toxin, which increases the risk of death. In New Zealand, indigenous non-target species most at risk from eating brodifacoum in cereal-based baits are herbivorous and omnivorous birds (e.g., weka, pukeko, and saddleback). The species most at risk from secondary poisoning are predatory and scavenging birds such as weka, Australasian harrier, southern black-backed gull, and morepork. Insectivorous birds, bats, lizards, and frogs are probably least at risk. However, laboratory and field trials are essential to determine the actual risks, and reduce scientific uncertainties. The risks of pest control must be carefully balanced against the benefits. These benefits can be substantial where introduced mammals threaten native species with extinction.
