The adrenocortical response to stress has been shown to be important in energy management of vertebrates. Although hummingbirds (Trochilidae) are useful models for studying energy balance, they are not amenable to traditional methods of studying hormones. In this study we report noninvasive methods for measuring and manipulating corticosterone (CORT), the principal stress glucocorticoid in birds. CORT was measured in cloacal fluid (CF) collected from unrestrained rufous hummingbirds… Expand
Corticosterone and Nocturnal Torpor in the Rufous
Three experiments were designed to investigate whether seasonal changes in the relations among energy chalcorticosterone (CORT), known to have a role in restoration of energy homeostasis, regulatesExpand
Corticosterone and nocturnal torpor in the rufous hummingbird (Selasphorus rufus).
TLDR
The hypothesis that CORT is involved in the regulation of torpor is supported, but it is suggested that some feature of the CORT signal other than concentration per se may be required to fully explain seasonal changes in the relations among energy challenge, CORT, and nocturnal torpor in hummingbirds. Expand
Corticosterone Metabolites can be Measured Noninvasively in Excreta of European Stonechats (Saxicola torquata rubicola)
TLDR
The results suggest that the corticosterone enzyme-immunoassay used in this study provides a quantitative measure of excreted corticosteroid metabolite levels in European Stonechats and has the potential to replace plasma measurements of these hormones. Expand
Circadian Rhythm and Stress Response in Droppings of Serinus canaria
TLDR
EIA could be used as a reliable noninvasive approach to monitor the stress induced by restraint conditions in Serinus canaria, and showed the greatest response at the beginning of the light period, followed by the absence of the peak usually recorded at the end of the dark phase. Expand
Sampling Effort/Frequency Necessary to Infer Individual Acute Stress Responses from Fecal Analysis in Greylag Geese (Anser anser)
TLDR
It was concluded that by increasing the number of fecal samples collected, the course of CORT could be measured more precisely and an individual's acute stress response inferred more reliably. Expand
Effects of ACTH, capture, and short term confinement on glucocorticoid concentrations in harlequin ducks (Histrionicus histrionicus).
TLDR
Serum cortic testosterone concentrations in wild harlequin ducks increased within min of capture and elevated levels were found for several hours post capture, indicating that surgery and confinement maintain elevated corticosterone concentrations in this species. Expand
Effects of corticosterone pellets on baseline and stress-induced corticosterone and corticosteroid-binding-globulin.
TLDR
Self-degradable pellets proved to be an efficient tool to artificially elevate circulating baseline corticosterone especially in field studies, requiring only one intervention. Expand
Fecal corticosteroids in a territorial bird selected for different personalities: daily rhythm and the response to social stress
TLDR
Evidence is provided for a physiological basis of different coping strategies in birds, emerging in response to social stress and with a pattern similar to that in other vertebrates. Expand
Effects of repeated, short-term, corticosterone administration on the hypothalamo-pituitary-adrenal axis of the white-crowned sparrow (Zonotrichia leucophrys gambelii).
TLDR
Repeated, acute administration of CORT resulted in higher baseline CORT levels and a down-regulation of the endogenous adrenocortical response to a standardized stress, and maximum CORT and plasma corticosterone binding globulin levels increased in response to the CORT treatments only at the end of the breeding season. Expand
Synthesis of Measuring Steroid Metabolites in Goose Feces
TLDR
To improve the sample handling during extraction and the assay sensitivity, the use of a group‐specific antibody against 17‐oxoandrogens that does not require deconjugation prior to the analysis is promoted, which robustly increased fecal corticosterone in all seasons. Expand

Corticosterone and nocturnal torpor in the rufous hummingbird (Selasphorus rufus).
TLDR
The hypothesis that CORT is involved in the regulation of torpor is supported, but it is suggested that some feature of the CORT signal other than concentration per se may be required to fully explain seasonal changes in the relations among energy challenge, CORT, and nocturnal torpor in hummingbirds.

Endocrine Responses of White-Crowned Sparrows to Environmental Stress
TLDR
The effects of selected assumed stressors on the plasma concentrations of corticosterone, luteinizing hormone, and sex steroid hormones in White-crowned Sparrows (Zonotrichia leucophrys) were assessed. Expand
Response of fecal cortisol to stress in captive chimpanzees (Pan troglodytes)
TLDR
Both fecal concentrations and proportionate increases in response to stress were significantly correlated with the corresponding values in urinary cortisol, confirming the stressfulness of these procedures and the stress responsiveness of fecal cortisol. Expand
Seasonal changes of the adrenocortical response to stress in birds of the Sonoran Desert.
TLDR
Analysis of plasma levels from black-throated sparrows, cactus wrens, and curve-billed thrashers indicated that at least some birds breeding in the open desert with restricted access to water are able to suppress the classical adrenocortical response to stress, and it is possible that this stress modulation may allow breeding to continue despite severe heat. Expand
Noninvasive corticosterone treatment rapidly increases activity in Gambel's white-crowned sparrows (Zonotrichia leucophrys gambelii).
TLDR
This method demonstrated that intermediate levels of corticosterone caused an increase in perch hopping in white-crowned sparrows within 15 min of hormone administration, which indicated elevated locomotor activity that is consistent with behavioral responses to natural perturbations. Expand
Corticosterone, foraging behavior, and metabolism in dark-eyed juncos, Junco hyemalis.
TLDR
Male, dark-eyed juncos, Junco hyemalis, were held in captivity under conditions simulating winter temperature and photoperiod and B implants resulted in higher plasma levels of B, which may be applicable to the advanced stage of stress in birds. Expand
Noninvasive fecal monitoring of glucocorticoids in spotted hyenas, Crocuta crocuta.
TLDR
Fecal steroid assessment is of use in monitoring adrenal activity in spotted hyenas because of the physiological relevance of fecal glucocorticoid metabolites and the high-performance liquid chromatography fractions analyzed by EIA showed various immunoreactive substances with polarities of unconjugated steroids. Expand
Evaluating adrenal activity in African wild dogs (Lycaon pictus) by fecal corticosteroid analysis.
TLDR
Fecal corticosterone immunoreactivity appears to reflect adrenal activity in the African wild dog and, therefore, may be useful for evaluating stress. Expand
ECOLOGICAL BASES OF HORMONE-BEHAVIOR INTERACTIONS : THE EMERGENCY LIFE HISTORY STAGE
TLDR
Field work reveals that changes in responsiveness to LPFs have ecological bases, such as reproductive state, body condition etc., that in turn indicate different hormonal control mechanisms in the HPA cascade. Expand
Seasonal Differences in the Response of Rufous Hummingbirds to Food Restriction: Body Mass and the Use of Torpor
TLDR
Seasonal differences in response to food restriction may reflect reduced stress response in these high-altitude, high-latitude breeders during the short breeding season, when the physiological and behavioral consequences of responding to environmental stress may interfere with breeding success.
