Grey partridge chick survival in the first two weeks of life is critical and directly tied to insect availability in farmland habitats devastated by pesticide use.
Grey partridge chicks unable to find sufficient insects in pesticide-treated farmland face starvation within days of hatching. Protein-deficient chicks grow poorly, have impaired thermoregulation, and die rapidly from cold and starvation. The welfare impact of widespread chick starvation across Britain's farmland is enormous in scale. Targeted agri-environment management creating insect-rich conservation headlands directly addresses this welfare failure, improving chick survival from as low as 20% to over 50% in well-managed areas.
