Yellowhammer breeding welfare is shaped by territory quality and the availability of nest sites in low dense shrubs adjacent to seed-rich feeding areas.
Yellowhammer chicks require abundant invertebrates in the first weeks after fledging. Intensively managed arable fields adjacent to nesting scrub may lack adequate insect food. Agri-environment schemes that create insect-rich margins adjacent to nesting scrub address both nest site and chick food needs simultaneously.
