The grey partridge has declined by over 90% since the 1950s and is one of the UK most severely threatened farmland birds, requiring comprehensive habitat management for recovery.
Grey partridge welfare is in crisis at population level with near-extinction from most former range. Individual birds in remaining strongholds depend on insect-rich cereal headlands, weedy stubbles, and predator management. Chick starvation in pesticide-treated crops without adequate insect food is the key welfare failure driving decline.
