Fig. 4. Influence of artificial sky temperature (TASK) on the temperature of the external surfaces of the skin (TSIW), insulation plumage (TPIW) and flight plumage (TPFW) according to air temperature (TAIR; 15°C in A,C,E, 25°C in B,D,F) and wind speed (UWIN; 0.3 m s-1 in A,B; 11 m s-1 in C,D; 20 m s-1 in E,F) during experimental phases 3 and 4. Dotted lines show observed mean values (N=4) while solid lines show values predicted from the regression models based on all measurements (Table 1).
