The grey partridge is one of Britain's most endangered farmland birds, with population declines of over 90% since the 1950s driven by agricultural intensification and reduced invertebrate abundance.
Grey partridge welfare is severely compromised by modern farming that has eliminated the diverse field margins, weed-rich stubbles, and insect abundance they need. Chicks that cannot find enough insects in their first few weeks face starvation and high mortality - a serious welfare concern. Adults nesting on the ground are vulnerable to predation and agricultural machinery. Conservation headlands - unsprayed strips around cereal field edges - have proven effective at restoring chick survival rates.
