“…However, correlations between energy expenditure and brood size are sometimes much less pronounced than expected, or even absent (TINBERGEN & VERHULST, 2000;VER-HULST & TINBERGEN, 1997;WRIGHT et al, 1998). WILLIAMS (1987), HAILS & BRYANT (1979) and MORENO et al (1995) could only show a correlation between feeding rate and DEE in one of the sexes. In his overview, BRYANT (1988) shows that ve out of nine studies cannot detect a positive relationship between energy expenditure and nest visit rate.…”

We measured energy expenditure in free-living great tits (Parus major) during the active (day) and the inactive period (night) with the aim of determining whether great tits compensate for energy costs made during periods of high activity in periods of low activity. If such compensation occurs, inferences from measurements of energy expenditure over a 24 h period, with regard to the energy costs of the different behavioural elements, may obscure relations between parental effort and energy expenditure. Also, energy budgets, based on estimates of time budgets combined with a xed cost for each behavioural category observed, may be unreliable if animals are able to compensate for energy costs made during periods of high activity in periods of low activity.Laboratory studies have revealed a reduction in resting metabolic rate (RMR) when birds are forced to work harder during the day, but it has not yet been investigated whether such nocturnal savings are also made under natural conditions.We manipulated brood size in a free-living population of great tits to create a difference in the demands of the nest, measured effort (feeding visits) and daily energy expenditure (DEE). In order to test whether compensation occurred we measured both DEE over 24 h, and resting metabolic rates (RMR) of female great tits at night. DEE and feeding rate differed between the experimental groups, being higher in females rearing enlarged broods, but we did not nd evidence of nocturnal saving.

“…As a starting point, parental effort was substituted by feeding rate but more recently by parental energy expenditure. Stimulated by the work of HAILS & BRYANT (1979) and DRENT & DAAN (1980) the research concentrated on the question whether and how energy expenditure limits reproductive output.…”

“…Development of the doubly-labelled water (0 2 0 18 ) technique for measuring rates of energy expenditure (Lifson et al 1955, Lefebvre 1964 has allowed the difficult problem of energy budgets in free-living birds to be investigated (Utter & Lefebvre 1970, 1973, Hails 1977, Hails & Bryant 1979. Availability of data of this type for a range of species will clearly allow more precise evaluation of energy flow in populations and communities than has been possible previously.…”

“…This value is significantly lower than comparable values of 2.8 for King Penguins Aptenodytes patagonicus (Kooyman et al 1982), 2.6 and 2.9 for Gentoo Pygoscelis papua and Macaroni Eudyptes chrysolophus Penguins (Davis et al 1983); 2.2 for Little Penguins ) and 2.6 for Jackass Penguins . Extensive studies of hirundines, for which flight costs are a significant portion of field metabolism, have yielded values between 2.2 and 5.3 (Hails & Bryant 1979).…”

At-sea metabolism (CO2 production) and water turnover of six breeding Grey-headed Albatrosses Diomedea chrysostoma were measured, using the doubly labelled water method, at Bird Island, South Georgia. Mean food consumption (estimated from a water influx rate of 1.01 1 d -' and data on dietary composition) was 12001: d^ ' or 50.4 W. At-sea metabolism (derived from a rate of COz production of 3.98 1 h-') was 27.7 W, 2.5 times the estimated basal metabolic rate (BMR). On average the birds ingested nearly twice as much food energy as they expended to obtain it. The metabolic rate during flight (estimated from at-sea metabolism and activity budget data) was 36.3 W (range 34.7-39.0 W) or 3.2 (range 3.Cb3.4) times the predicted BMR. This is the lowest cost of flight yet measured, but consistent with the highly developed adaptations for economic flight shown by albatrosses. These results are briefly compared with data for other polar vertebrates (penguins, fur seals) exploiting similar prey.A significant part of the costs to parents of rearing offspring is the energy consumed in foraging activities. These costs are likely to be particularly important in species which need to travel long distances (e.g., because they feed on widely dispersed resources) and in species using energetically expensive modes of locomotion (e.g., flapping flight). Although field studies of energy expenditure have been carried out on a variety of birds and mammals (e.g., Mullen 1970, Utter & Lefebvre 1972, Shoemaker et al. 1976, Bryant & Westerterp 1983, little attention has been given to species adapted for long-distance travel. Of birds, pelagic seabirds of the Order Procellariiformes contain many such species and pre-eminent amongst these, in terms of specializations for economy of long-distance flight, are the albatrosses Diomedeidae, which are essentially dependent on soaring and gliding (Pennycuick 1975(Pennycuick , 1982(Pennycuick , 1986. T h e metabolic rate during free-ranging gliding flight has not yet been estimated for any bird; the energy costs of foraging trips have not been measured for any procellariform and there is only one previous study of a seabird, the Sooty T e r n Sterna fusrata (Flint & Nagy 1984).We used the doubly labelled water method, coupled with behavioural and dietary data, to measure the rate of water and energy flux in breeding Grey-headed Albatrosses Diomedea chrysostoma making foraging trips to sea from Bird Island, South Georgia (54"00'S, 38'02'W) during the austral summer of 1983-84. This species has been extensively studied at this site and much information is available on its reproductive biology and ecology (reviewed in Prince 1985), including unique data on activity budgets at sea (Prince & Francis 1984).
