Data and code from: Staying sheltered: geographical variation in nestbox use by a nocturnal raptor outside the breeding season

Datasets supporting the manuscript “Staying sheltered: geographical variation in nestbox use by a nocturnal raptor outside the breeding season”. These datasets contain observations of nestbox use by a nocturnal raptor outside the breeding season, together with environmental, habitat, and breeding-season variables collected from monitored nestboxes. The data are organized into three complementary files. The first file, “Dataset_revision”, contains aggregated observations by nestbox, year, and season (autumn and winter), including information on monitoring effort, nestbox occupancy, playback surveys, environmental conditions (temperature, wind speed, day length, rainfall, and snow depth), bird community census data, and surrounding habitat composition. The second file, “Onelinepicture”, contains data at the individual image level, where each row corresponds to a single camera-trap photograph with associated nestbox ID, date-time information, and recorded owl presence/absence inside the nestbox. The third file, “Breeding_season_correlation”, contains nestbox occupancy information during the breeding season across multiple years, allowing comparisons between breeding and non-breeding season use patterns. For the analyses presented in the associated manuscript, information from these datasets was combined using R.
