| Tartalmi kivonat: | Eurasian woodcock is a popular migrating game species in Hungary and in several European countries. For its wise management it is essential to collect reliable information of the breeding, wintering and also migrating populations. The aim of this study was to describe and analyze the differences among the monitoring methods used in different countries, and to give advices to improve the methods of data collection and evaluation of the monitoring system running in Hungary. Our study is based on the comparison of monitoring programs run in France, Russia, Belarus and in the Archipelago Azores. The key factor of all such surveys is the display behaviour of male birds, which is called roding. However there are some differences between them. We evaluated the different monitoring methods on the basis of scientific literature considering the place, time and duration of survey sessions, the collected data and the methods of their analysis. The main cause of differences is the different aim of the different studies. Hungary cannot obviously be taken as a breeding or wintering area, it rather plays an important role in migration. The aim of the monitoring in Hungary is to follow and characterize the flow of migration, and to estimate the minimal number of birds crossing our countries borders. The evaluation of data in Hungary is also different. However the methods of observations and the quantity of collected data allow us to evaluate our data in a similar way. It would be essential if we would like to compare our results to the results of other monitoring programs in Europe. |
