New research suggests badgers are one of the main threats to the survival of red-listed ground-nesting birds including lapwing and curlew, and that the risk of nests being predated increased during cold or dry weather when their stable diet of earthworms is less accessible.
One study, a comprehensive review of camera trap data from across the UK, provides the clearest picture yet of which animals are responsible for nest predation in Britain. Of 2,088 nests included in the analysis 29.2% were predated. Wader nests were most often predated by mammals. Badgers were responsible for 41.7% of wader nest predation, followed by foxes at 23%.
Andrew Hoodless Director of Research at the GWCT, which contributed data to the study alongside other organisations including RSPB, Essex Wildlife Trust and Wildfowl and Wetlands Trust, said: “Continued improvement and restoration of habitat is critical for wader conservation, but without predation management it can be in vain. This paper provides a valuable picture of the scale and nature of predation pressure across important bird breeding sites and will help inform management strategies for the protection of ground-nesting species. It also raises questions around how we tackle the threat from protected predators such as badgers. Non-lethal control methods, such as temporary electric fencing of nest sites, can be effective but are not always practical. Lapwing have declined by 53% with the loss of around 110,000 pairs in the UK since the mid-1990s, and there are now only estimated to be 300-450 pairs of nesting curlew south of Birmingham. Both species face local extinctions, whereas generalist predator populations have increased and are high relative to most other European countries. Given the urgent need to save some of our most iconic birds, we may need to make some difficult choices about licensing the control of certain species in particular circumstances, in order to protect others before it’s too late.”
