The Rose-ringed Parakeet

Uit de laatste, zeer succesvolle, decembertelling blijkt dat er sprake is van een spectaculaire toename van de aantallen Halsbandparkieten, tot bijna een verdubbeling van het vorige maximum: ongeveer 21.000 vogels in Nederland.

Birds in The Netherlands

Thanks to the national bird counts, Sovon has insight into the development of numbers of Dutch bird species, their distribution and developments in areas important to birds, such as Natura 2000 areas.

The information is based on the monitoring networks that Sovon Vogelonderzoek Nederland coordinates in collaboration with Statistics Netherlands (CBS) and other organisations. The basis of the monitoring is formed by the Ecological Monitoring Network (NEM), to which regional and provincial monitoring networks are linked. The monitoring is made financially possible by the central government and the provinces. The information on this website is supplemented by the atlas projects carried out by Sovon, including Vogelatlas and LiveAtlas. The information is updated at least annually and is free to use provided that the recommended source is acknowledged graphs and www.sovon.nl is mentioned. See also the explanation with more details (in Dutch) about the results displayed.
