Table 1.
Top 10 pigeon proxy models ranked by AIC. ‘IQR’, ‘VAR’, ‘MED’, ‘SUM’ are used to indicate that the model is the interquartile range, variance, median and area under the curve of each property. The estimated degrees of freedom (EDF) indicate the extent to which relationships are linear, with values closer to 1 describing a linear fit and closer to 2 curvilinear.
