We investigated whether environmental temperature has any causal role in the winter fattening in certain finches of the subfamily Carduelinae. Correlational analyses between fat content of American goldfinches (Carduelis tristis) and various short- and long-term measures of temperature provide no evidence for a proximate role of this environmental variable in determining the degree of fattening of these birds in southeastern Michigan. Their fat content shows the best correlations (r = −.61 to… 

A Comparison of Winter Stress Responses in Cardueline Finches

Interspecific differences in stress-induced elevation of plasma corticosterone and the relationship with body condition are consistent with a possible role of this hormone in modulating foraging activities and, perhaps, local movements of carduelines in response to environmental factors.

SEASONAL ACCLIMATIZATION IN THE AMERICAN GOLDFINCH REVISITED: TO WHAT EXTENT DO METABOLIC RATES VARY SEASONALLY?

The view that prominent winter increases in Msum and BMR are components of winter acclimatization in American Goldfinches from South Dakota and that seasonal changes in metabolism in goldfinches are similar to those for other small temperate-wintering birds is supported.

Winter fattening in the dark-eyed junco: plasticity and possible interaction with migration trade-offs

Results suggest that platticity in a life-history trait has evolved in an uncertain winter environment through environment-dependent fattening and post-breeding migration in dark-eyed juncos.

Multiple regression analyses of midwinter fattening of the white-throated sparrow

Fattening in response to weather conditions appears to be a form of "fine-tuning" of energy reserves superiniposed on a more stable, intrinsic cycle of winter fattening.

Standard Metabolic Level and Insulative Characteristics of Eastern House Finches, Carpodacus mexicanus (Müller)

Analysis of thermal conductance for MI-OH house finches indicates a significantly higher insulation value in winter than in late spring, a circumstance the authors ascribe to more worn plumage in the latter season, suggesting some linkage between severity of winter climate and metabolic level.

Fattening strategies in dominance-structured greenfinch (Carduelis chloris) flocks in winter

The results suggest that fattening strategies in greenfinches depend on social status, and subordinates may be forced to carry larger reserves than dominants to safeguard against social constraints in access to food during critical times.

Experimental Evidence for Temperature-Dependent Winter Lipid Storage in the Dark-Eyed Junco (Junco hyemalis oreganus) and Song Sparrow (Melospiza melodia morphna)

Findings support the proximate-temperature hypothesis and corroborate similar experiments in Wisconsin juncos that repeatedly showed a direct fattening response to low proximate temperatures in environmental chambers, and juncos in both British Columbia and Washington showed significant inverse correlations between winter fat and proximate temperature.

Metabolic Acclimatization to Cold and Season in Birds

The goal is to characterize metabolic acclimatization by birds to cold and season to an extent commensurate with current knowledge of this form of compensation.

VARIATION OF BODY MASS IN MOORHENS

In birds body mass changes should reftect a tracte-off between costs and benefits of energetic storage (Witter & Cuthill, 1993). Benefits include lowered probability of starvation and of thermal

Food restriction decreases thermoregulation in the silky starling Sturnus sericeus (Aves: Passeriformes)

Results indicate that silky starlings can decrease their energy metabolism during periods of food shortage by making a suite of adjustments from the organismal to the biochemical level, which could be adaptations that allow starlings to adjust to seasonal changes in food abundance.

Winter Fat Deposition and Overnight Survival of Yellow Buntings (Emberiza citrinella L.)

A study of yellow buntings caught at a roost at Wytham, near Oxford, in the winter of 1966-67 reports the levels of fat and other energy reserves carried by the birds on different dates, and these reserves are related to the calculated energy requirements for each night to determine the proportion of birds which should survive each roosting period.

Metabolic adjustments of small passerine birds for migration and cold.

It is evident that the complex processes of migration and winter acclimatization are intimately linked with the metabolic properties of the highly aerobic skeletal muscle contained within the flight apparatus of passerines.

The intensive deposition of fat that occurs during migration in many species of birds is one of the most impressive examples of adaptive obesity that has yet been discovered among wild animals and is an adaptation primarily to the energy requirements of migratory flight.
