Organisms may respond to rapid human induced environmental changes by adapting their habitat requirements through behavioural flexibility. In human-modified landscapes from southern Belgium, recent management activities have generated structurally different and novel land-use types that are now occupied by a number of farmland bird species. However, as birds rely on environmental cues to select their habitat, they can be subject to maladaptive habitat selection if these cues become uncoupled from the underlying habitat quality. We therefore used the European Stonechat Saxicola torquatus as a model species to compare the relative attractiveness and breeding quality of the three main land-use types occupied by farmland birds (i.e. intensive grassland, Christmas tree plantations and clear-cut patches in plantation forests) in order to test whether habitat selection is adaptive in a changing landscape. Between 2014 and 2018, we examined the settlement pattern of territorial males to measure habitat preference and we recorded key parameters reflecting reproductive performances and individual survival to assess the quality of the three land-use types for the reproduction of the stonechats. Our results indicate that stonechats preferentially settle in clear-cut patches where they produce lower-quality offspring due to a gradual decrease of nestling body conditions during the breeding season. However, we found that this has no consequence on recruitment rates, because first-year survival was not related to nestling body conditions in our study system. As other parameters of reproductive performances, adult survival and first-year survival were similar between the three land-use types, we concluded that stonechats are capable of flexible habitat use and may find breeding opportunities of similar quality in the three land-use types although these strongly differ in terms of vegetation structure and management. Moreover, our results highlight the importance of measuring multiple fitness components to assess habitat quality in a comprehensive way. [less ▲]

Over the last decade, the conversion of annual-rotation based crops or grassland areas into non-food perennial crops has been increasingly prevalent in European farming systems. This shift is associated with major changes in management practices and has created new environmental conditions and resources for wildlife. Impacts on birds have been examined for bioenergy agricultural systems, such as miscanthus plantations and short-rotation willow coppice. However, they remain largely unknown for Christmas tree plantations (CTPs) that have recently increased considerably in some European countries. We examined the extent to which CTPs alter bird species assemblages in the farmland areas of southern Belgium, where they mainly replace intensive grassland. The abundance of birds was recorded during the breeding season in randomly selected sites located in grassland and in CTP. Results show that introduction of CTP into landscapes dominated by grassland with low hedge densities locally increases bird species richness and abundance without leading to biotic homogenization. Differences in species richness and abundance between grassland and CTP decrease with increasing hedge densities. A community analysis indicates that the plantation of Christmas trees enriches the bird assemblage of intensive grassland areas. In intensive grassland with few hedges, small-size CTPs could constitute an option to increase structural heterogeneity and provide new potential breeding conditions for some farmland birds. However, questions remain about the genuine quality of the resources available in CTP and further research is needed to examine the breeding success and survival of birds that settle in this type of habitat.

Over the last decade, nonfood perennial crops have been increasingly prevalent in European farming systems. Here, vegetation structure and crop management greatly differ from conventional crops and may likely impact farmland birds. Impacts on birds have been examined for bioenergy agricultural systems, such as miscanthus plantations and short rotation willow coppice. In Europe, the extend of Christmas tree plantations (CTP) has recently increased dramatically in farmland but their impacts on farmland birds remains largely unknown. We examined the extent to which CTP in southern Belgium alter bird species assemblages compared to traditional farmland. The presence and abundance of birds were recorded twice during a breeding season in randomly selected sites located in farmland areas with and without CTP. Results show that the conversion of traditional farmland into CTP modifies bird species assemblages and locally increases bird diversity and density without inducing biotic homogenization. This observed pattern indicates that CTP might constitute an interesting alternative habitat for farmland birds. However bird presence or abundance may be confounding indicator of habitat quality because individuals may be attracted to low-quality habitats in human modified landscapes. The European Stonechat Saxicola rubicola was chosen as a model species to investigate the quality of CTP as a breeding habitat in more details. Habitat quality in CTP was assessed with measures of reproductive success and survival. These measures were compared with those collected in traditional farmland. Although vegetation structure, field management and nest placement are highly different between habitat types, our first results suggest that CTP are not of lesser quality than traditional farmland for the European Stonechat.
