Yellowhammers have declined severely on UK farmland due to changes in farming practices, with agri-environment measures offering targeted recovery.
Yellowhammers on farmland without appropriate food sources face starvation during winter when invertebrate prey is unavailable. The loss of winter food sources has caused population collapse. Agri-environment measures that restore overwinter stubbles and seed-rich field margins directly improve individual bird welfare by ensuring food availability during the most challenging season.
