}SummaryThe Black-capped Chickadee,Parus atricapillus, is a year-round resident of deciduous forests near Ithaca, New York. Chickadees are confronted with high nightly energetic demands, due to their small size (10–12 g) and the subfreezing winter temperatures, which must be met by an adequate energy reserve. The fat stores of Chickadees on midwinter evenings provide slightly more energy then expended overnight, as based on metabolic measurements made in the laboratory.The Chickadee has a much…

Seasonal Metabolic Acclimatization in Mountain Chickadees and Juniper Titmice
- Biology, Environmental SciencePhysiological and Biochemical Zoology
- 2002
Chickadees and titmice show metabolic acclimatization similar to other temperate species, and dry mass of contour plumage increased in winter for both species and was associated with decreased thermal conductance in winter chickadee compared to summer chickadees.

The physiology of hypothermia in the black-capped Chickadee,Parus atricapillus
- BiologyJournal of comparative physiology
- 2004
The physiology of hypothermia in chickadees is similar to torpor; however, chickadee did not arouse to a normal diurnal body temperature in the laboratory, and their hypotheria was not induced by inanition or prolonged exposure to cold, as reported for other species capable of torpor.
Daily variation in markers of nutritional condition in wintering Black-capped Chickadees Poecile atricapillus

The results suggest that these markers can be used as indicators of energy turnover in resident wintering passerines, suggesting higher fat catabolism and fattening rates in mid-winter.
Evidence of facultative daytime hypothermia in a small passerine wintering at northern latitudes
- Biology, Environmental Science
- 2014
It was found that Tb of individual birds was lower when captured at low Ta, reaching values as low as 35.5 °C in actively foraging individuals, and daytime hypothermia does not result from individuals being unable to maintain Tb during cold spells or to a lack of body reserves.
Forest fragmentation and body condition in wintering black-capped chickadees
- Environmental Science
- 2008
This work investigated whether forest cover affects body condition in a population of black-capped chickadees (Poecile atricapillus (L., 1766)) during winter, and measured residual body mass, fat score, and rate of growth of induced feathers to assess body condition.
Winter fattening strategies of two passerine species: environmental and social influences
- Environmental Science
- 1995
The use of space and the social structure of the wintering populations seem to affect fattening strategies: fat reserves of resident Robins were negatively related to the density of conspecific migrants, early in the season and the same relationship was not observed for Wrens, which were dispersed in extensively overlapping home-ranges.
Nocturnal hypothermia and metabolism in the Willow TitParus montanus at 63° N
- Environmental ScienceJournal of comparative physiology
- 2004
The Willow Tits showed a marked seasonal variation with regard to the depth of hypothermia achieved when they were exposed to different ambient temperatures, whereas mid-winter acclimatized birds showed almost no response and a steady gradient was found between these two extremes.

Metabolic rather than insulative adjustments appear primarily responsible for the acclimatization of American goldfinches and pine siskins to winter conditions in the northern United States.

It is suggested that the mtDNA‐nDNA mismatch of hybrids may produce less efficient mitochondrial protein complexes, which in turn affects the efficiency of ATP production, thereby increasing rate of oxygen consumption to meet ATP demands.

- Environmental Science, BiologyThe American Naturalist
- 1966
It appears at least equally plausible that the low environmental temperature of winter must be regarded as the primary ultimate factor in winter fattening, and the proximate factor, or battery of proximate factors, involved in the physiological regulation of fat storage in winter remain an open question.

The adaptive significance of winter fattening in the Bullfinch Pyrrhula pyrrhula nesa (L.) is assessed by analyses of the weights and body composition of 134 individuals caught in Wytham Woods, near Oxford, England, between mid-October, 1966, and mid-January, 1967, from a resident population whose ecology had been studied since 1961.

In winter in the north during the daylight hours, birds move about in search of food and general muscular activity produces sufficient heat to maintain body temperature, but at times of inactivity during the day or especially at night when birds are inactive, increased muscle tone and shivering appear to be the only methods available for producing heat.
