Identifying predators of eggs and chicks of Lapwing Vanellus vanellus and Black‐tailed Godwit Limosa limosa in the Netherlands and the importance of predation on wader reproductive output
Farmland bird populations in the Netherlands have shown an accelerating decline in recent years, despite extensive conservation efforts including reserves, agri‐environment schemes and protection of nests by volunteers. Although agricultural intensification is the main cause underlying these decline...

Farmland bird populations in the Netherlands have shown an accelerating decline in recent years, despite extensive conservation efforts including reserves, agri‐environment schemes and protection of nests by volunteers.
