Note: Each model is a log ratio explanatory variable with individual bird identification specified as a random effect. 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.
