The effect of ambient temperature on the relationship between ventilation and metabolism in a small parrot (Agapornis roseicollis)

Abstract

Values for basal metabolism, standard tidal volume (VT), standard minute volume (\(\dot V_{\text{I}} \)), and mean extraction efficiency (EO2) in the thermal neutral zone (TNZ) inAgapornis roseicollis (1.84 ml·min−1; 0.95 ml·br−1, STPD; and 33.3 ml·min−1, STPD; and 22.5%; respectively) were all very similar to values for these parameters previously measured inBolborhynchus lineola, a similarly sized, closely related species from a distinctly different habitat.
