Grey partridges are severely declining farmland birds where welfare depends on both reducing predation pressure and restoring the arable habitats and invertebrate food sources that chicks require.
Grey partridge welfare is threatened by the combined effects of predation pressure and food deprivation for chicks. Nest predation by foxes, stoats, and corvids destroys entire clutches and kills incubating females. Chick starvation from insecticide-related invertebrate declines in the critical first fortnight of life causes a slow death by malnutrition. Surviving chicks in food-poor environments grow more slowly and have compromised immune systems making them vulnerable to disease. The severe overall decline means that local populations are too small to recover from normal mortality events, creating demographic welfare problems that affect entire local populations.
