Temperature regulation in Turkey Vultures

Temperature regulation by six Turkey Vultures (Cathartes aura) was studied at ambient temperatures (Ta) from 11 to 400C in a metabolic chamber. Within this range body temperature varied little, averaging 39.70C, and the ratio of CO2 production to 02 consumption averaged 0.76. The thermal-neutral zone (TNZ) extended from 26 to 400C. Below 260C evaporative water loss and the heat-transfer coefficient were minimal, reflecting maximum insulation, and breathing and heart rates remained nearly…

Nocturnal Variation in Body Temperature of Griffon Vultures

The decline in body temperature at night was significantly greater in food deprived birds, which at 10.5 days post-feeding had dropped by 4-6°C, and it is suggested that this is an adaptation to reduce energy requirements of Griffon Vultures during periods of food shortage.


Abstract Turkey Vultures (Cathartes aura) and Black Vultures (Coragyps atratus) were observed at a day perch in south-central Pennsylvania during winter of 1984–85 to determine whether there were

Energy metabolism and body temperature in the Griffon Vulture (Gyps fulvus) with comparative data on the Hooded Vulture (Necrosyrtes monachus) and the White-backed Vulture (Gyps africanus)

The Ta-independent MR is the largest yet measured in birds and may function as an additional and very effective mechanism for saving energy.

Seasonal Behaviour Adaptation of Broilers with Anatomical Interpretationduring Summer Heat Stress

This study was conducted to show the seasonal behavioral changes with some anatomical interpretation to the heat-exchange system. The study applied on 200 one day old broiler chicks, 100 reared in

Neck-drooping Posture in Oriental White-Backed Vultures (Gyps bengalensis): An Unsuccessful Predictor of Mortality and Its Probable Role in Thermoregulation

In contrast to the highly seasonal pattern of neck-drooping, mortality of vultures occurred in all months of the year, indicating that neck- Drooping has low specificity and sensitivity as an indicator of poor health and impending death in vulture.

Cooling requirements fueled the collapse of a desert bird community from climate change

Water requirements for evaporative cooling are increasingly likely to drive population declines, providing a physiological basis for climate-driven extinctions as climate change spreads warm, dry conditions across the planet.

Turkey Vulture Breeding Behavior Studied with Trail Cameras

Abstract We report initial findings on Turkey Vulture (Cathartes aura) breeding behavior from nests in abandoned buildings in Saskatchewan. We used infrared trail cameras placed at three nests

Temperature regulation in the Black Vulture

The area of featherless skin on the head and neck changed with the body temperature, thus indicating a role in heat dissipation, and it is concluded that these featherlessskin areas can be adjusted according to the need for temperature regulation.

Heat regulation and metabolism in some tropical mammals and birds.

The mouse and the squirrel were good thermoregulators with a critical temperature of about 27° C, whereas the opossum, armadillo and three-toed sloth were bad regulators.

Energy expenditure for thermoregulation and locomotion in emperor penguins.

The data suggest that walking 200 km (from the sea to the rookery and back) requires less than 15% of the energy reserves of a breeding male emperor penguin initially weighing 35 kg.

Body temperature regulation in red-tailed hawks and great horned owls: responses to air temperature and food deprivation

Comparing the thermoregulatory responses of Red-tailed Hawks and Great Homed Owls to changes in air temperature and weight loss as a test of their metabolic adaptations to winter conditions found them to be similar to other birds of prey.

Oxygen Consumption and Respiratory Evaporation of the Emu and Rhea

Crawford (1965) proposed a tentative equation relating these variables in birds: evaporative water loss per unit weight and body weight, which conforms to a pattern similar to that for metabolism and body Weight.

Spread-winged posture of turkey vultures: single or multiple functions?

The behavior and spread-winged postures of Turkey Vultures (Cathartes aura) were examined at a communal roost near Superior, Arizona, from April-June, 1979, to determine the significance of wing-spreading.

The data indicate that overwintering Bald Eagles are effective at exploiting and conserving energy.
