Résumé

The BMR (6.00 ml O2·min?1) and thermal conductance (0.235 ml O2·min?1·°C?1) ofAmazona viridigenalis, a medium sized parrot, are close to allometrically predicted values for nonpasserine birds, but theT 1c of 26.5 °C is 8.5 °C higher than predicted (Fig. 1). Minimal respiratory frequencies measured in four species of birds average 60% of the rate predicted by a previous equation and yield the relationship, breaths·min?1= 10.3 kg?0.32. Frequencies are very dependent upon the methods used to obtain the data (Fig. 3). ‘Resting’ values of respiratory parameters are poorly defined in the existing literature, and there are no single resting values within the TNZ analogous to a BMR. Rather values change within, as well as below and above, the TNZ. Minimal values of different parameters occur at differentT a's, not necessarily within the TNZ (Figs. 2, 4, 5). For clarity, resting respiratory parameters should be reported as standard values, analogous to standard metabolic rates, withT a specified. In birds the pattern of ventilation (f andV T) changes asT a changes resulting in different extraction efficiencies at a given minute volume (Figs. 6, 7). This facilitates adjustment to both changing oxygen demands and changing thermoregulatory needs.
