“…1999). Azure‐winged Magpies nested in association with Japanese Lesser Sparrowhawks in the 1990s but did so only rarely in the 2000s (Ueta 2007). The population of one of the Magpie's main predators, the Jungle Crow Corvus macrorhynchos , increased in the 2000s, as did their rate of intrusion into Sparrowhawk territories, which meant that the Sparrowhawks had to defend their territories more frequently but did so less intensively.…”

Exploiting the nest defence behaviour of another relatively aggressive species is one of the most unusual amongst a great diversity of strategies used by animals to evade predation. Here we review 62 studies that have looked at protective nesting associations in which at least one species is a bird. Most ‘protected’ associates are found in the Anseriformes, the Charadriiformes and the Passeriformes, while most ‘protective’ associates come from the Charadriiformes and the Falconiformes. Protected associates primarily benefit from a reduced predation rate when nesting near protective species although a variety of other, often unusual benefits have been described, including early warning of predators, lower parasitism, lower brood‐parasitism, nest stability and higher mating success. Protected associates sometimes also pay costs when they or their young are killed by their aggressive associate, or when they are forced to abandon their nest. Two studies demonstrate that protected species manipulate the trade‐off between the costs and benefits of nesting near an aggressive associate, while only a handful of studies have found specific adaptations to help avoid costs. In contrast, there is little evidence to suggest that the protective associates pay costs or gain benefits. This is probably because few researchers set out to test this hypothesis specifically, but we tentatively conclude that the majority of nesting associations are commensal in nature, and that only a few are parasitic or mutualistic. Many studies show that nesting associations occur by active choice and not because the associate species choose similar habitat, but only one study does so experimentally. In two cases the nesting association is obligatory for one of the species but there was also evidence for significant local adaptation to nesting near protective species, sometimes across a broad geographical range. Finally, we identify potential pathways that may have led to the evolution of nesting associations, discuss some possible implications for the populations involved and argue that nesting associations provide many novel research opportunities.

“…Birds are important components of urban biodiversity (Wiklund 1982;Bogliani et al 1999;Quinn and Kokorev 2002;Ueta 2007;Whelan et al 2015), among which highlyabundant and synurbic species such as the common pigeon (Columba livia) are perhaps the clearest examples of birds that thrive in urban environments. Urban bird communities can also include raptors, which provide a suite of important ecosystem services.…”

Living in the concrete jungle: a review and socio-ecological perspective of urban raptor habitat quality in Europe

Raptors can be important components of urban ecosystems due to their role as apex predators, the presence of which may bring benefits to people. Urban environments may provide good quality habitats, and the raptors’ ability to utilize resources found here can contribute to their success. However, urban environments are socio-ecological systems and such mechanisms shaping habitats and ecological resources therein are less understood. This paper explores how raptors utilize urban resources, and the socio-ecological processes influencing their quality and availability. It begins with a systematic mapping of the literature to summarize the utility of urban resources by raptors with European distributions. Eighteen species were documented in the literature successfully exploiting novel hunting and/or nesting opportunities in both green and built-up locations of urban areas. We discuss how these may be consequential of human activities, some of which intentionally provided as subsidies, and how their utility by raptors create opportunities for human-raptor interactions further shaping public perception and decisions which potentially affect the raptors. Finally, we demonstrate these concepts by drawing on our experience from an urban peregrine falcon (Falco peregrinus) conservation site in London, UK. The paper concludes with a call for urban raptor conservation and research to consider social and ecological aspects together, appropriately reflecting urban environments as socio-ecological systems.

We found that barn swallow (Hirundo rustica) breeding occurs within close proximity to humans. An evaluation of barn swallow breeding frequency and the breeding success rate of swallows at research sites, which were buildings inhabited by humans and buildings where humans had previously resided, was conducted in order to establish a relationship between the location of barn swallow nests and human habitation and activity frequency. The results demonstrated that barn swallows often breed in human-inhabited buildings. No significant relationship was observed between the wall material and the direction of the wall and the type of building, whereas a much higher proportion of the nests were located near doors with a high level of human movement. In addition, no significant correlation was observed between the location of the nest and the distance from potential resources (food, water etc.), however, a statistically significant relationship was observed between the frequency of human activity measured through the video camera and the number of nests located at a certain distance. The average number of offspring and the reproductive success rate were higher in nests located within close proximity to human activity compared to nests not located within close proximity to human activity, suggesting that the presence of humans had a positive effect on reproduction. This study show that barn swallow nesting occurs in locations where there is a human influence and humans provide implicit protection of swallows from predation, which has a significant impact on breeding.
