We investigated whether daily O2, consumption (Vo2) could be predicted from heart rate (f(H)) in five exercising barnacle geese (Branta leucopsis) and compared the accuracy of this method with that of the doubly labeled water (DLW) method. The regres

We estimated energy requirements for plumage replacement in the kestrel (Falco tinnunculus) by comparing O2 consumption Vo2 and metabolizable energy intake during molt and nonmolt. The energy expenditure for feather synthesis (S) as derived from the

Measurements of basal metabolic rate (BMR), body water, fat, and lean dry mass of different organs were obtained in 22 bird species, ranging from 10.8 to 1,253 g body mass. Residuals of BMR (after subtracting BMR allometrically predicted from body ma

Basal metabolic rate in the field vole (Microtus agrestis) was studied in relation to body composition and daily energy expenditure in the field Daily energy expenditure was measured by means of doubly labelled water ((D2O)-O-18). In the same individ

We studied the limiting factors for brood size in the kestrel, Falco tinnunculus, by measuring parental effort in natural broods of different size and parental response to manipulation of food satiation of the brood. Parental effort was quantified as

During directional flight trained Eurasian Kestrels (Falco tinnunculus) in the laboratory expended 13.8 W. Free-living birds expended 14.6 W during nonsoaring flight that included both directional flight and wind hovering. The former value was obtain

We measured the Heat Increment of Feeding (H) as the difference in oxygen consumption between the fed and fasting state in the kestrel at different ambient temperatures. Total H is a constant fraction of metabolizable energy intake and amounts to 16.

In order to survive and grow, neonates need to remain homeothermic. However, in the arctic, which is mostly regarded as a harsh environment with prevailing low ambient temperatures, achievement of homeothermy for chicks might cause problems. The smal

The relationship between body size and basal metabolic rate (BMR) in homeo therms has been treated in the literature primarily by comparison between species of mammals or birds. This paper focuses on the intraindividual changes in BMR when body mass
