Ensuring the conservation of birds is frustrated by their tendency to range over large areas (Choi et al. 2015, Runge et al. 2015). This can be exacerbated by habitat fragmentation which typically causes an increase in foraging range (Haskell et al. 2002). Conservationists may counter such human-wildlife conflict by providing supplementary food, an action that is also practiced by the public (Robb et al. 2008). Indeed, such actions have allowed for the re-establishment of Red Kites Milvus milvus in the UK (Orros & Fellowes 2015); can increase breeding productivity (Robb et al. 2008) and have been cited as the reason for the success of vultures in the Western Palearctic relative to populations elsewhere (Donázar et al. 2009). This strategy is not without its shortcomings though; a dependency on human-supplied food can have disastrous consequences if the supply is terminated (Donázar et al. 2009). It has also been linked to changes in foraging behaviour, disease spread and territory defence behaviour (Robb et al. 2008 and references therein).
