Biophysical model results in Australia (Simpson Desert). a Estimated reductions in evaporative water loss due to high NIR (40% vs 10% reflectivity) under different combinations of solar radiation and humidity. Higher values (warmer colours) indicate a higher percentage of water saved by having higher plumage reflectivity; grey values (closer to zero) indicate no difference. Values estimated for three different sizes. b Aridity index values and mid-distribution points for the 90 species in our data set; bars contain ~50% of 1000 data points. The green star shows the location from which climate forcing data were obtained for the biophysical model. The map was extracted from the Atlas of Living Australia (www.ala.org.au)
