The common snipe has declined significantly as a UK breeding bird, dependent on wet grassland with soft soil for probing invertebrate prey and rank vegetation for nest concealment.
Snipe in drained grassland cannot access earthworm prey when soil is hard, causing nutritional stress during chick-rearing when energy demands peak. Nests concealed in vegetation are vulnerable to predation; loss of rank grass through heavy grazing exposes nests. Nest trampling by livestock causes egg and chick mortality with direct welfare costs to breeding adults that have invested in incubation.
