...Roland Parkes; Lewis G. Halsey; Anthony J. Woakes; Roger L. Holder; Patrick J. Butler SUMMARY The rate of oxygen uptake at the surface between dives was measured for four tufted ducks, Aythya fuligula , during bouts of foraging dives to a depth of 1.8 m. The ducks surfaced into a respirometer box...

... with lung air during dives, we measured differential pressures between the interclavicular and posterior thoracic air sacs in five diving tufted ducks Aythya fuligula . The peak differential pressure between posterior thoracic and interclavicular air sacs, 0.49±0.13 kPa (mean ± S.D.), varied substantially...

...R. M. Bevan; E. Keijer; P. J. Butler ABSTRACT Tufted ducks, Aythya fuligula, were trained to dive for different durations in shallow tanks using a computer-controlled system of lights. The birds were rewarded with food for a correct response, i.e. performing a dive of the required duration. When...
