“…Following Cramer (2009), we used a value based on Miller and Eadie's (2006) allometric predictive equation for all dabblers (RMR = 514.98 kJ/bird/day). An alternative approach was to average the four historic published values of black duck RMR (Hartung 1967;Berger et al 1970;Wooley and Owen 1977;Bennett and Harvey 1987), which derived a lower value (RMR = 414.75 kJ/day/bird) than Miller and Eadie's (2006) dabbler specific RMR, resulting in a lower estimate of DEE A . We ultimately felt more confident with the higher estimate and larger sample size provided by Miller and Eadie's (2006) dabbler specific allometric prediction in comparison to the small sample size and wide range (Range: 309-523 kJ/day/bird) of the black duck specific values of RMR.…”

“…The RMR value was either the allometrically derived value (DEE ADabbler 514.98 kJ/bird/day) from Miller and Eadie (2006) as used in equations 1 and 2, or a black duck specific RMR (DEE ABlackDuck 414.75 kJ/ bird/day) calculated by averaging the four published values of RMR for black ducks (Hartung 1967;Berger et al 1970;Wooley and Owen 1977;Bennett and Harvey 1987). The term "3" is the estimated increase of RMR used to account for the energetic cost of free-living (Purol 1975;Prince 1979;Heitmeyer 1989).…”

“…Two common approaches to calculating DEE for waterfowl are predictive allometric equations or a time-energy budget. Both methods rely upon an estimate of resting metabolic rate (RMR), which for black ducks, was historically estimated through a series of respirometry studies (Hartung 1967;Berger et al 1970;Wooley and Owen 1977;Bennett and Harvey 1987). Miller and Eadie (2006) proposed an allometric equation that predicted an average RMR for dabbling ducks based on a correlation with body mass.…”

SUMMARYHumboldt penguins Spheniscus humboldti in captivity and free-living Magellanic penguins S. magellanicus were fitted with loggers to determine beak angles during breathing. The Humboldt penguins were also fitted with masks for determining rates of air flow during breathing. During periods of higher gas exchange requirement, Humboldt penguins opened their beaks during inspiration, where tidal volume was linearly correlated with both change in beak angle and maximum beak angle, closed them slightly during the final stages of inspiration and finally closed them during expiration. Substantial differences were apparent between individuals. Contrary to the condition proposed for most birds, our data suggest that expiration is passive during periods of high respiratory tidal volumes, and that the increased resistance of the respiratory pathway serves to slow air flow so as to maximize gas exchange in the lungs. During foraging, Magellanic penguins at the surface between dives showed similar breathing patterns but maximum beak angles were much higher and breath cycle time shorter, as would be expected for animals attempting to maximize gas exchange. Both maximum beak angle per breath and breath frequency changed systematically over the surface pause; both were initially high, then decreased to a low before rising again to a maximum just before diving. Based on known changes in tidal volume with beak angle derived from Humboldt penguins, a simple model is proposed to examine rates of gas exchange over the surface pause. This indicates that the observed patterns do not maximize the rate of transfer of oxygen over the whole of the surface pause but are rather concerned with an initial rapid accumulation of oxygen in the tissues followed by effective carbon dioxide release.

“…Mammals and birds during activity are also capable of increasing oxygen consumption by an average of five-to tenfold (14,15). The levels of aerobic metabolism achieved by endotherms are thus considerably in excess of those attained by lower vertebrates.…”

Resting and maximal levels of oxygen consumption of endothermic vertebrates exceed those of ectotherms by an average of five- to tenfold. Endotherms have a much broader range of activity that can be sustained by this augmented aerobic metabolism. Ectotherms are more reliant upon, and limited by, anaerobic metabolism during activity. A principal factor in the evolution of endothermy was the increase in aerobic capacities to support sustained activity.
