A new paper by our research network has been published on Bird Study. The paper highlights the importance of using field protocols during counts of migrating birds and the need of sharing objectives and best practices among monitoring groups working in migratory bottlenecks. Moreover in the paper are reported case studies to show how can be useful to use a radar on migratory bottlenecks. First in order to localize focal points of passage, second to calculate the percentage of raptors passed undetected by visual observers, and last to evaluate the proportion of raptors undertaking the sea crossing on coastal areas.
