Insectivorous farmland passerines have declined steadily throughout most of western Europe over the past decades. The Whinchat Saxicola rubetra, an insectivorous passerine species of grassland, has undergone one of the most dramatic declines among farmland birds. The recent intensification of farming practices has led to a decrease in the availability of grassland invertebrates in general, and of important Whinchat chick-food in particular, even in remote Alpine valleys. This has a negative effect on reproductive success.
