dc.description.abstractIncreasing land-use intensification in recent decades has led to the loss and subdivision of large pristine areas, which generally affects species' presence and abundance. However, not every species responds equally to land-use changes: vulnerability of species to landscape transformation may be conditional on their degree of plasticity in habitat use. To assess the behavioural modifications that enable bird populations to persist after landscape management, we compared habitat selection patterns of Red-necked Nightjars (Caprimulgus ruficollis) in two close (10 km) but contrastingly-managed areas in southwestern Spain. Macro-scale analyses showed that nightjar activity (i.e. nesting, roosting and foraging) was dependent on land cover type. In both the unmanaged and the managed area, open shrublands were positively selected as nesting habitat, whereas pinewood patches in the unmanaged area were replaced by pine tree plantations as roosting habitats in the managed property. Individuals in both areas used paved and unpaved roads as the main foraging habitat. Nevertheless, marshlands and lowlands in the unmanaged area were replaced by irrigated fruit tree plantations as secondary foraging habitats in the managed property. The micro-scale analysis showed that nightjars in the unmanaged site sat preferentially nearby autochthonous Juniperus phoenicea trees to hawk flying insects in short upward sallies from the ground, whereas birds commonly used tall dense exotic trees (e.g. Acacia saligna, Nicotiana galuca, Casuarina equisetifolia) in the managed property. Based on similarities in body condition of nightjars and on their greater abundance in the managed area compared to the unmanaged site, we conclude that species tolerant to anthropogenic alterations (i.e. having high plasticity in habitat choice) could to some extent cope with or even benefit from moderate landscape transformation.
