| Summary: | Within the UK’s largest lowland Eurasian Curlew Numenius arquata population, curlew preferentially nested on physically disturbed (treated) than undisturbed (control) grassland, and low nest survival rates were primarily attributable to predation by Red Fox Vulpes vulpes . To inform conservation interventions for Curlew within semi-natural lowland dry-grassland landscapes. Across a 3700 ha lowland dry-grassland landscape, over two years, effects of ground-disturbance management on Curlew nest placement ( n = 41) were examined using generalized linear models controlling for vegetation strata. The effects of site and management on nest survival ( n = 44) were also examined, controlling for lay date and year. Nest predator identity was investigated using temperature sensors ( n = 28) and nest cameras ( n = 10). Curlews were five times more likely to nest on physically disturbed than undisturbed grassland. Nest survival (overall mean ± se = 0.24 ± 0.07) was not influenced by year or ground-disturbance but ... |
