Counting birds is difficult in the eternally singing forests of Siberia. Can the Dutch birdwatchers help out there?

Counting birds in Siberia is challenging due to the dense forests. Recently, Dutch birdwatchers observed a nutcracker in the Waterleidingduinen, highlighting the current invasion of these birds in the Netherlands. This phenomenon occurs every few years, likely due to food shortages in their Siberian habitat. Nutcrackers are not migratory but can appear in other regions when conditions are unfavorable. The article discusses the complexities of biodiversity counting, especially regarding invasive species, and suggests that Dutch birdwatchers could assist in Siberia's bird counting efforts.
