“…In contrast, studies report a negative relationship between the perception of conflict and bird abundance, partly due to people's greater appreciation of rare than abundant species (Ballejo et al., 2020; Esmaeili et al., 2019; Gaston et al., 2018). Although we did not find direct linkages between the extent of HBCs and other bird ecological traits (e.g., aggregation behavior, clutch size, home‐range size, and migration patterns) reported in the HBC literature, we suggest that some relationship may potentially exist and should be explored in further local, regional, and global analyses of HBCs (Charles & Linklater, 2013; Linz & Hanzel, 2015; MacLeod et al., 2011). Although we only refer to HBCs associated with material damage, we believe that it is important to expand on functional traits of cultural interest in future studies (Almuna et al., 2020; Echeverri et al., 2020).…”

Because of the significant impacts on both human interests and bird conservation, it is imperative to identify patterns and anticipate drivers of human–bird conflicts (HBCs) worldwide. Through a global systematic review, following the PRISMA 2020 guidelines, we analyzed the socioeconomic factors and bird ecological traits driving the degree of knowledge and extent of HBCs. We included 166 articles published from 1971 to 2020 in our analyses through which we built a profile of the socioeconomic conditions of 52 countries with reported conflicts and the ecological traits of the 161 bird species involved in HBCs. Although HBC expanded worldwide, it had the greatest impact in less‐developed countries (estimate 0. 66 [SE 0.13], p< 0.05), where agriculture is critical for rural livelihoods. Species with a relatively greater conflict extent had a relatively broader diet (estimate 0.80 [SE 0.22], p<0.05) and an increasing population trend (estimate 0.58 [SE 0.15], p<0.05) and affected human interests, such as agriculture and livestock raising. In countries with greater biodiversity, HBCs caused greater socioeconomic impacts than in more developed countries. Our results highlight the importance of understanding and addressing HBCs from multiple perspectives (ecological, sociocultural, and political) to effectively protect both biodiversity and local livelihoods.

Summary 1.Organic farming is often promoted as a solution for counteracting the adverse impacts of agricultural intensification on biodiversity. However, it is unclear whether the biodiversity benefits derived from organic farming require an adoption of organic farming in its entirety (i.e. a systemslevel approach) or whether the benefits derived are because of just a small subset of the associated management practices. 2. Using bird survey data collected from kiwifruit orchards in New Zealand, we assessed whether orchards managed under an organic system support higher bird densities than those under integrated management systems. To determine whether biodiversity gains might also be achieved on non-organic orchards, we tested whether variation among kiwifruit orchards in the amount of (non-crop) woody vegetation cover, density of shelterbelts and toxicity of pesticide applications are better predictors of bird densities than management systems. 3. Composite measures of breeding season densities of all native species and the subset of native insectivores were higher on organic orchards than integrated management orchards. Densities of introduced bird species were comparable among management systems. 4. Pesticide use and habitat composition variables were better predictors of native bird densities than management system, with native bird densities negatively associated with pesticide toxicity ranking and ⁄ or positively associated with woody vegetation cover. 5. Synthesis and applications. A complete conversion to an organic system may not be required to improve biodiversity in agroecosystems. Instead, the transfer of specific land management practices known to benefit biodiversity in organic systems has the potential to enhance biodiversity in other more intensively managed systems (e.g. integrated management). This may be a path towards attaining biodiversity benefits at a larger scale, because such changes may be more straightforward than conversion to an organic system.

“…To minimize the negative impact of birds to crop harvest, a shift in management practices considering landscape structures such as high trees seems necessary and habitat management is recommended to potentially control populations of birds acting as agricultural pests (MacLeod et al, 2011). Our results show that farmers should avoid growing crops, which are susceptible to seed predation by birds, adjacent to high trees (tree height > 5 m) and if possible decide to grow crops which are not likely to suffer from seed predation by birds closer to high trees.…”

Natural habitats in agricultural landscapes promote agro-ecosystem services but little is known about negative effects (dis-services) derived by natural habitats such as crop seed predation. Birds are important seed predators and use high landscape structures to perch and hide. High trees in agricultural landscapes may therefore drive seed predation. We examined if the presence, the distance and the percentages of high trees (tree height >5 m) and the percentages of natural habitat surrounding sunflower fields, increased seed predation by birds in Israel. At the field scale, we assessed seed predation across a sample grid of an entire field. At the landscape scale, we assessed seed predation at the field margins and interiors of 20 sunflower fields. Seed predation was estimated as the percentage of removed seeds from sunflower heads. Distances of sample points to the closest high tree and percentage of natural habitat and of high trees in a 1 km radius surrounding the fields were measured. We found that seed predation increased with decreasing distance to the closest high tree at the field and landscape scale. At the landscape scale, the percentage of high trees and natural habitat did not increase seed predation. Seed predation in the fields increased by 37%, with a maximum seed predation of 92%, when a high tree was available within 0-50 m to the sunflower fields. If the closest high tree was further away, seed predation was less than 5%. Sunflower seed predation by birds can be reduced, when avoiding sowing sunflowers within a radius of 50 m to high trees. Farmers should plan to grow crops, not sensitive to bird seed predation, closer to trees to eventually benefit from ecosystem services provided by birds, such as predation of pest insects, while avoiding these locations for growing crops sensitive to bird seed predation. Such management recommendations are directing toward sustainable agricultural landscapes.
