Note: Each model is a generalised linear mixed model with individual bird identification as a random effect. The null model does not include any vegetation openness metric. ΔAIC is the difference in AICc from the minimum AICc model. The term ‘Chenopod’ was used to refer to all species in the family Chenopodiaceae, except the genus ‘Sclerolaena’ which was analysed separately.
