“…We selected three taxa, exerting the main crop damages excluding ungulates. Birds (especially the European starling Sturnus vulgaris) are, after wild boar, the main cause of crop loss in our study area (Santilli et al 2012;Laurenzi et al 2016). Among mammals, the crested porcupine Hystrix cristata may exert heavy damage to vegetable gardens (Laurenzi et al 2016;Lovari et al 2017) and the red fox Vulpes vulpes may cause severe losses in poultries (Poole 2002).…”

Are wildlife value orientations useful tools to explain tolerance and illegal killing of wildlife by farmers in response to crop damage?

Understanding human-wildlife conflicts and monitoring their consequences, such as wildlife persecution, is crucial for biological conservation. Although most theoretical models suggest that the influence of value orientations on behavior is mediated by higher order constructs such as attitudes and norms, wildlife value orientations are widely used to assess human-wildlife relationships and to predict human behavior towards wildlife. We have no evidence of studies which have measured them in Mediterranean countries, where the highest biodiversity level in temperate Document type: Accepted version of the final paper, in line with the journal guidelines about the embargo (https://www.jdb.uzh.ch/id/eprint/23071/) Western countries is present. In spring 2016, we administered a questionnaire to local farmers in Central Italy to measure the association be tween wildlife value orientations and illegal killing of wildlife, in response to crop or poultry damages (n = 352). We obtained the prevalence of illegal killing with the Randomized Response Technique, ensuring complete individual protection to respondents. We modeled the effect of wildlife value orientations over illegal wildlife killing with a Bayesian logistic regression for three taxa: the red fox, the crested porcupine, and birds, as most of persecution by farmers in our study site is exerted towards them. We found that domination predicted illegal killing for the red fox only. On the other hand, mutualism predicted tolerance towards all the study taxa. Combining wildlife value orientations and the Randomized Response Technique can be a promising approach to explore human-wildlife conflicts and their consequences. Furthermore, the Mediterranean setting of our study filled existing geographical gaps about wildlife value orientations in Europe. We encourage future research on the application of wildlife value orientations to conflicts involving wildlife and extensive farmers, i.e., at large scale, as well as future large-scale research on wildlife value orientations in Europe

“…Bomford (1990) concluded that a tape acoustic device is ineffective on European starlings (Sturnus vulgaris), as well as Conover and Dolbeer (1989) for reflective strips on blackbirds. Santilli et al (2012) tested a helium balloon on maize and sunflower fields with good results. Blackwell et al (2002) observed a limited effect of lasers on common pigeons (Columba livia), but better on American crows (Corvus brachyrhynchos).…”

Bird damage to sunflower: international situation and prospects

Bird damage to sunflowers (Helianthus annuus) degrades the profitability of this crop and calls into question its place in rotations. Our international literature review shows that sunflower is one of the crops most vulnerable to bird attacks. However, these predatory pests are not specialized: if the sunflower is affected in one region, then the other crops sharing the same cycle could also be affected to varying degrees. All production areas are affected by flowerhead damage at maturity. Damage at emergence has recently become more visible in France, Italy and Switzerland, probably as a result of global changes and evolving farming practices. Birds are highly mobile pests with complex behaviour. The problem needs to be tackled in a hierarchical framework that takes into account field, landscape, and regional scales, along with processes at different timescales from rapid field selection to long term demographic trends. Moreover, the distribution of damage is asymmetrical: few fields are affected, but with a high severity. At this time, there is no single effective method for preventing damage, and coordination at the landscape scale should be initiated to find potential solutions. Finally, there is a gap between theoretical and applied knowledge, even though initiatives in North America have helped to move research forward. These difficulties imply an integrated approach combining partially effective methods, the association of several stakeholders, and the coordination of several policies (agricultural, environmental, and recreational hunting or wildlife management). Additionally, data collection appears essential to acquire knowledge about economic damage and efficacy of control programmes. Digital technology can be useful for such purposes. Finally, this review advocates international networking to consolidate a research community on this topic and on the wider issue of bird damage to crops.
