Wilson's storm-petrels are the smallest endotherms (mean mass ca. 40 g) living and breeding in the cold climate of Antarctica and might therefore be expected to require unusually large amounts of food and energy. We studied the energetics of this species by measuring rates of oxygen consumption in captive birds and rates of CO₂ production in free-living storm-petrels (doubly labeled water method) during the breeding season. Basal metabolic rate (BMR) was 2.15 ± 0.09 cm³ O₂∙g⁻¹∙h⁻¹, equivalent… Expand
Basal Metabolic Rate of Adult Leach’s Storm-petrels During Incubation
TLDR
Lower metabolic rates in incubating Procellariformes compared to those of non-reproducing birds measured at the same temperature suggest decline in metabolism is possibly related to metabolic depression due to fasting. Expand
Reproductive Energetics and Prey Harvest of Leach's Storm‐Petrels in the Northwest Atlantic
TLDR
Population energetics modelling indicated that during a 7—mo breeding period Leach's Storm—Petrels at colonies in the northwest Atlantic Ocean consume >74 000 Mg of prey, mostly myctophids and amphipods (mostly Hyperia galba), as wall as euphausiids (mostly Meganyctiphanes norvegica) and other prey (decapods, copepods, isopods).

Effect of Wind on Field Metabolic Rates of Breeding Northern Fulmars
TLDR
The high energetic cost of flapping flight during windless conditions may explain patterns of nest attendance: in particular, why nest site attendance by Northern Fulmars in winter is greater during calm weather. Expand
Energy Expenditure in Adult Least Auklets and Diving Petrels during the Chick-Rearing Period
TLDR
The low gross foraging efficiency and high DEEs of the auklet and diving petrels suggest that the high energetic cost of foraging and food delivery to the nest constrains brood size, as surface-feeding seabirds had lower relative energy expenditures. Expand
Activity-specific metabolic rates of free-living northern gannets and other seabirds
TLDR
Statistical analyses of metabolic rates of free—living seab birds indicated that rates are elevated in seabirds in cold—water regions and inSeabirds that use flapping flight, but do not vary with phylogenetic order. Expand
Energy expenditure and food consumption by breeding Cape gannets Morus capensis '
Gannets (genus Morus) are piscivorous seabirds with a breeding distribution restricted to the cool to temperate waters of the mid latitudes. Field metabolic rates of breeding Cape gannets M. capensjsExpand
Food and feeding ecology of Wilson's storm petrel Oceanites oceanicus at South Georgia
TLDR
A review of storm petrel diets emphasizes the importance of fish to Oceanodroma species and of crustaceans to Oceanites, Garrodia and Pelagodroma. Expand
Diet Composition, Reproductive Energetics, and Productivity of Seabirds Damaged by the Exxon Valdez Oil Spill
TLDR
In some forage fishes, size, month, reproductive status, or location contributed significantly to intraspecific variation in energy density, which may affect diet selection of breeding seabirds especially. Expand
Ventilatory Oxygen Extraction in Relation to Ambient Temperature in Four Antarctic Seabirds
TLDR
The data suggest that increasing Eo2, as a means of reducing ventilatory heat loss is not a general phenomenon in cold-adapted birds. Expand
A New Storm-Petrel Species from Chile
TLDR
The new taxon's foraging ecology and behavioral habits are unique among the southern Oceanitinae, including “mouse-runs” and repeated diving beneath the surface to retrieve food items. Expand

Energy Utilization by Free-Ranging Jackass Penguins, Spheniscus Demersus
TLDR
Rates of CO2 production by breeding Jackass Penguins (mean mass, 3170 g) were measured by using doubly labeled water and foraging efficiency (the metabolizable energy gained while foraging . the energy used during foraging) was 2.1 for birds with small chicks. Expand
Energy Cost of Incubation to the Parent Seabird
TLDR
The knowledge of incubation energetics has increased dramatically in the last decade since King and Kendeigh first presented their cost-of-incubation theories, and extensive studies combining both field and laboratory methods conducted on seabirds nesting on remote oceanic islands have facilitated these studies. Expand
Energy Costs of Incubation and Moult in Petrels and Penguins
TLDR
Data support the present assumption that only about half the material lost during these fasts is fat, the rest being mainly water, and that the daily energy cost of incubation in petrels and penguins is about 1.4 times the estimated cost of basal metabolism. Expand
Field Energetics and Foraging Mode of Kalahari Lacertid Lizards
TLDR
The widely foraging lizard Eremias lugubris made a greater profit on its investment, and the wide forager grew nearly twice as fast as did the sit-and-wait predator during this study. Expand

Metabolic rate during flight of Sooty Terns was determined to be 4.8 times standard metabolic rate (SMR), much lower than estimates of flight metabolism predicted from previously published equations. Expand

TLDR
Three major areas in the energetics of free-ranging adult seabirds are addressed: basal metabolism, locomotion, and energy budgets. Expand
Daily energy expenditure and water-turnover rate of adult European starlings (Sturnus vulgaris) during the nesting cycle
TLDR
The maximum daily energy expenditure for females was about four times predicted BMR, similar to values reported in other studies, and water-turnover rates paralleled CO2 production over the nesting cycle, the average values for each sample varying between 0.048 and 0.070 per h. Expand

TLDR
Samples from waters around South Georgia in 1978 contained 10–11% protein, 2–6% lipid, 0.3–0.6% carbohydrate, 2% chitin, and 3–4% mineral ash, which varied greatly with sexual maturity. Expand
Physiological responses of the giant hummingbird, Patagona gigas.
TLDR
Results show that rates of entry into and arousal from torpor are inversely related to body weight, and evaporative water loss is inverselyrelated to ambient water vapor pressure at ambient temperature of 25°C. Expand
