Environmental variables: TAIR air temperature, TASK artificial sky temperature, UWINwind speed; surface temperatures of the pigeon: TPFWflight plumage of the wing, TPIW insulating plumage of the wing, TPIB insulating plumage of the back, TSIW insulating plumage of the wing skin.
The database includes a total of 2850 values of T measured in 4 pigeons during experimental phases 3 and 4. T values are in K and UWIN in m s−1.
Full model r2 are shown below intercept values.
Regression coefficients (all significant at P<0.002) are shown above their partial r2.
