Fig. 3

The interaction between humidity and maximum temperature influencing bill surface area for 36 species passerine from the Meliphagoidea (n = 2867 individuals). Humidity is mean summer water vapour pressure (hPa) and temperature is mean maximum summer temperature averaged for the preceding 5 summers prior to capture; summer is defined as the months December to February. Colours represent categories of bill surface area
