Notes: a is the allometric coefficient and b is the scaling exponent from equation BMR = aMb, where BMR is basal metabolic rate in kJ/day and M is body mass in kg. PC means “phylogenetically corrected.” Temperate birds here include also species from high latitudes.
aMarks recalculations based on equation 1 L of O2 = 20.083 kJ of energy (Schmidt-Nielsen 1997).
