SummaryAmerican goldfinches (Carduelis tristis) were observed roosting in Colorado blue spruce (Picea pungens), which comprised part of a mixed stand of conifers. Their winter roost-sites were distally situated among the most densely-needled branches on the leeward sides of these trees. Heated and unheated taxidermic goldfinch mounts were placed within these sites and at the same height in an adjacent clearing. The radiative and convective characteristics of these locations were monitored… 

Wintering forest birds roost in areas of higher sun radiation

We analyze environmental determinants of roost site selection by tree gleaning passerines wintering in a Mediterranean montane oakwood at a craggy area of high variation in altitude and hill-shading

Temperature characteristics of winter roost-sites for birds and mammals: tree cavities and anthropogenic alternatives

TLDR
The results suggest that orchard habitats in winter show a spatiotemporal mosaic of sites providing different thermal benefits varying over time and in relation to ambient temperatures, and tree cavities provide significantly higher thermal benefits than nest boxes or wood stacks.

Western Specialty : Plumbeous and Cassin ’ s Vireos

As part of an 11-state inventory, we censused the Double-crested Cormorant (Phalacrocorax auritus) in the interior of California from 2009 to 2012, using a combination of aerial, ground, and boat

Ratios of colony mass to thermal conductance of tree and man-made nest enclosures of Apis mellifera: implications for survival, clustering, humidity regulation and Varroa destructor

TLDR
Experimental research has found that the heat transfer rate is approximately four to seven times greater in the hives in common use, compared to a typical tree enclosure in winter configuration, implying improved survival in hives with thermal properties of tree nests.

Microhabitat characteristics related to seasonal roost switching: implications from a threatened and introduced cockatoo species in an urban landscape

Background Communal roosting is a common avian social behaviour, which potentially provides foraging benefits, predation avoidance or thermoregulation in birds. To identify the crucial environmental

Selection of roosting vegetation in the great tit, Parus major, during the winter period

TLDR
Individuals of Parus major usually roost in cavities during winter time but open roosting in tree vegetation is also known and the thermal pattern was statistically significant when only considering the use of the less protective (leafy) shelter.

Microclimate of tree cavities during winter nights—implications for roost site selection in birds

TLDR
Cavities in healthy trees were warmer than those in dead trees, but this difference disappeared with rising mean ambient temperatures, and the predictors of microclimate may provide indirect cues to prospecting birds.

Roost site selection by Little Owls Athene noctua in relation to environmental conditions and life-history stages

TLDR
It is suggested that adequate roost sites, such as multi-entrance tree cavities, are an important habitat requirement for Little Owls and that habitat quality can be affected by manipulating their availability.

Standard Operative Temperatures and Thermal Energetics of the Antelope Ground Squirrel Ammospermophilus leucurus

TLDR
Findings strongly support the interpretation that the thermoregulatory strategy of A. leucurus involves cycles of transient hyperthermia followed by periods of passive heat dissipation underground, which is three to four times the rate of metabolic heat production for active individuals.

Seasonal acclimatization to temperature in cardueline finches

TLDR
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.

Energetics of the Straling (Sturnus Vulgaris) In a Pine Woods

TLDR
Of the microclimate factors measured, only the wind velocity varied significantly between the recordings obtained outside of the pine woods and in areas within the woods that were used exten- sively as roost sites.

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

TLDR
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.

Selection of appropriate microclimates is generally thought to be an important component of avian behavioral thermoregulation. For many species, the winter night is perhaps the most thermally

Mid-Winter Lipid Reserves of the Golden-Crowned Kinglet

TLDR
It is hypothesized that such a bird might not be able to carry sufficient energy stores to maintain high body temperatures over long, cold, winter nights, and that nocturnal hypothermia must occur if the species is to survive.

Seasonal acclimatization to temperature in cardueline finches

TLDR
Increased stores of body lipid and muscle carbohydrate and the ability to mobilize these substrates rapidly during cold stress seem to be key factors in the superior thermogenic capacities of winter goldfinches.

Tolerance of Cold and Bergmann's Rule

As size is well known to affect the energy relations between an endotherm and its environment, one would expect that size may also influence or be related to geographic distribution. Bergmann's Rule

Geographic Variation in Mid-Winter Body Composition of Starlings

TLDR
Mid-winter body composition of a partially migratory species, the Starling, collected during mid-winter from a 2,800-km longitudinal range in the eastern United States showed significant geographic variation in body weight, feather weight, wing length, culmen length, tarsus length, lean dry weight, lipid weight and lipid index.
