For a subsample of these birds, inferences were ground-truthed against field observations. Variation in home range sizes at different stages of the breeding season, movements during the chick-rearing period, and the extent to which birds nesting in different habitats utilised the range of habitats available, were examined. The results show that inferring breeding outcomes from GPS data can generate useful information on breeding success, home range size, and habitat use that would be difficult to capture using other methods. 

The work also demonstrates that in areas subject to landscape-scale predator control, as is common in the Yorkshire Dales National Park, well-targeted, field- and farm-level interventions aimed at mitigating potential negative impacts of agricultural operations (especially harvesting silage) and high stocking densities could significantly increase breeding productivity for Curlews and other ground-nesting birds.
