Respiratory Exchange and Evaporative Water Loss in the Flying Budgerigar
1. Oxygen consumption of 2 budgerigars ( Melopsittacus undulatus ) was measured during level, ascending and descending nights lasting 5-20 min. in a wind-tunnel at speeds between 19 and 48 km./hr. InExpand
Control of Changes in Body Temperature, Metabolism, and Circulation by the Agamid Lizard, Amphibolurus barbatus
TLDR
Limited capacity for physiological thermoregulation may exist, and since such a capacity could have theoretical implications for the evolution of homeothers, this work considers whether this capacity should be focused onizards or other reptiles. Expand

  • 15 June 1970
TLDR
The minimum cost of transport for various walking, running and flying animals is functionally related to the type of transport and to body weight, and the same functional relations hold for poikilotherms and homeotherms, and for five or more decades of body weight. Expand
Bird Metabolism During Flight: Evaluation of a Theory
TLDR
Four modifications are made to Pennycuick9s (1969) theory for the energetic requirements of avian flight that improve the agreement between the theoretical predictions and existing measurements for flying birds and bats. Expand

BODY DRAG, FEATHER DRAG AND INTERFERENCE DRAG OF THE MOUNTING STRUT IN A PEREGRINE FALCON, FALCO PEREGRINUS
TLDR
This study describes techniques for measuring the interference drag generated by (a) the drag balance and mounting strut together and (b) the mounting strut alone, which may reduce the apparent body drag by more than 20%. Expand
Flight Speeds of Birds in Relation to Energetics and Wind Directions
RECENTLY it has become possible to measure accurately the power expenditures of birds flying freely in a wind tunnel (Tucker, 1968, 1969). The measurements show that power expenditure is influencedExpand
Aerodynamics of Gliding Flight in a Falcon and Other Birds
TLDR
The ‘equivalent parasite area’ method used by aircraft designers to estimate parasite drag was modified for use with gliding birds, and empirical data are presented to provide a means of predicting the gliding performance of a bird in the absence of wind-tunnel tests. Expand
