A synthesis of Eurasian Curlew (Numenius arquata arquata) demography and population viability to inform its management
The European population of Eurasian Curlew Numenius arquata arquata, a nearthreatened wader subspecies, has undergone pronounced population declines over the past 30 years. To assess the demography and viability of its global population, we surveyed studies quantifying demographic rates (productivit...

Adult survival, estimated at 0.90, was the most sensitive parameter determining population growth rates, but the low productivity levels over the last few decades seems to be the most probable cause of population declines.
