“…Hunting estates were managed to improve small game populations, mainly by the provision of supplementary food and water, and predator control. Direct shooting and live trapping with cages and neck snares are the methods most used for legal fox culling (Delibes‐Mateos et al ., ; Díaz‐Ruiz & Ferreras, ). In central Spain, there is a high variation in the use of these management measures among hunting estates (Arroyo et al ., ).…”

“…We evaluated the plasticity of red fox daily activity in environments with varying levels of prey availability, habitat structure and human disturbance (e.g. fox control and distance to human settlements) in Mediterranean areas of central Spain, where fox control is a widespread game management tool (Delibes‐Mateos et al ., ; Díaz‐Ruiz & Ferreras, ). According to previous studies on mammal predator activity we expected that foxes would adapt their activity pattern to that of their preferred prey at least where this is highly available, but that this behavioral pattern could be disrupted by other factors, such as habitat composition or human disturbance.…”

Drivers of red fox (Vulpes vulpes) daily activity: prey availability, human disturbance or habitat structure?

Daily activity patterns in mammals depend on food availability, reproductive stage, habitat selection, intraspecific interactions and predation risk, among other factors. Some mammals exhibit behavioral plasticity in activity patterns, which allows them to adapt to environmental changes. A good example of this can be found in the red fox Vulpes vulpes. This species is adapted to living in highly humanized environments, where it is often culled because it may affect human interests (e.g. through the consumption of game species or livestock). We assessed the potential main drivers of the daily activity patterns of the red fox in 12 Iberian Mediterranean areas through the use of camera traps. Among drivers, we considered main prey availability (European wild rabbits Oryctolagus cuniculus), degree of human disturbance (e.g. distance to human settlements, and intensity of predator control) and habitat structure. Our results revealed a predominantly crepuscular and nocturnal activity of foxes with local variations. Although overall fox activity increased with rabbit availability, the temporal overlap with prey activity was on average low, because foxes increased activity when rabbits decreased theirs (twilight-night). Red fox activity rhythms seemed to be determined by human presence where human disturbance is high. In addition, diurnal activity decreased in areas with higher levels of human disturbance (closer to human settlements and high predator control intensity) and increased in dense habitats. Our study shows that daily activity patterns of highly adaptable species are determined by several interacting drivers, resulting in complex behavioral patterns. This suggests that further ecological studies should consider different factors simultaneously for a better understanding of daily activity patterns of wildlife in different landscapes.

“…In Europe, Magpies are considered as a harmful bird species by some conservationists and hunters because of their predation on eggs and chicks of songbirds and gamebirds , Herranz 2000. As a consequence, control of Magpie populations is widespread in Europe (Hadjisterkotis 2003, Chiron & Julliard 2013, Díaz-Ruiz & Ferreras 2013. In Spain, Magpie control is mostly performed by hunters and game managers, who consider these birds as highly efficient predators of nests of Red-legged Partridges Alectoris rufa (Delibes-Mateos et al 2013, Díaz-Ruiz & Ferreras 2013, a small game species of socio-economic relevance (Díaz-Fernández et al 2012).…”

Capsule Feeding habits of the Black-billed Magpie are of interest for researchers, conservationists and hunters since magpies are considered as predators of eggs and chicks of both songbirds and gamebirds. Aims To characterize the feeding habits of magpies during their breeding season in agricultural environments of central Spain, and to assess the occurrence and incidence of birds and eggs in the magpie's diet. Methods Diet was determined by the analysis of gizzard contents from 118 culled magpies. The diet was described as the frequency of occurrence (FO) and the percentage of volume (VOL) of a certain food item and for each gizzard. Results Magpies presented a generalist diet, which included a wide range of foods. Arthropods and cereal seeds were the most frequently consumed food groups (FO > 60%). Eggs and birds were consumed only occasionally (FO < 6% and 17%, respectively; percentage of volume, VOL < 4%). Conclusion Our findings suggest that other birds and their eggs do not represent an important food for magpies in Mediterranean agricultural environments under the conditions found during this study. Nevertheless, more complex studies in different scenarios (i.e. different population sizes of magpies and prey), and over longer temporal scales, are still necessary to clarify this controversial issue.
