Birds are constantly responding to stimuli from their environment. When these stimuli are perceived as threatening, stress responses are initiated, with activation of the hypothalamo-pituitary-adrenal axis and the release of corticosterone from the adrenal gland. The basic emotion of fear is also experienced during a stress response. Corticosterone stress responses and behavioural responses to stimuli vary markedly between individual birds, raising questions about the significance of these…

Corticosterone, fear behaviour and plasma corticosterone responses to stressors in Japanese quail : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Physiology at Massey University, Palmerston North, New Zealand
Corticosterone had marked effects on the physiology of quail for several weeks after treatment ended, suggesting that chronic elevations in plasma corticosterone resulting from climate change or human disturbance could have negative affects in birds even after exposure to a stressor ends.
Relationships between personality traits and the physiological stress response in a wild mammal
The results do not support a strong association between the behavioral and physiological stress responses but show that in wild populations, where animals experience varying environmental conditions, the GC endocrine response and the expression of personality are uncorrelated traits among individuals.
Stress in Birds
Differences in stress reactivity between zebrafish with alternative stress coping styles
Animals experience stress in a variety of contexts and the behavioural and neuroendocrine responses to stress can vary among conspecifics. The responses across stressors often covary within an
Stress activity is not predictive of coping style in North American red squirrels
The hypothesis that physiological and behavioral stress responses are correlated in wild adult North American red squirrels is tested and it is found that FCM concentrations were not correlated with three measures of behavioral coping styles (activity, aggression, and docility) among individuals, supporting the “two-tier” hypothesis.

Corticosterone and fear behaviour in white and brown caged laying hens
The study has shown the value of measuring endocrine and behavioural variables together to provide objective data on characteristics of different strains of hens, and the first description of plasma corticosterone responses to handling over 60 min for caged laying hens on a commercial farm.
Variation within and between birds in corticosterone responses of great tits (Parus major).
It is demonstrated that corticosterone responses to a stressor tend to be repeatable in individual great tits, and a method for quantifying variation in cortic testosterone responses for comparison with other birds in the future is provided.
Modulation of the Adrenocortical Responses to Acute Stress in Arctic Birds: A Possible Ecological Basis
Comparisons of the increases in plasma levels of corticosterone following capture in several taxa of arctic birds indicated that suppression of the adrenocortical response to acute stress was not ubiquitous, and comparative data from free-living arctic Birds suggest an ecological basis for modulation of the cortisol responses to stress.
Fear and Fearfulness in Animals

The great variability in behavior and in physiological patterns generally associated with emotional reactivity is described, suggesting that fearfulness could be considered a basic feature of the temperament of each individual, one that predisposes it to respond similarly to a variety of potentially alarming challenges but is nevertheless continually modulated during development by the interaction of genetic traits of reactivity with environmental factors, particularly in the juvenile period.
The stress response systems: Universality and adaptive individual differences
Heritable variation for aggression as a reflection of individual coping strategies
Evidence is presented in rodents, that individual differences in aggression reflect heritable, fundamentally different, but equally valuablealternative strategies to cope with environmental demands.
Short-latency stressor effects on tonic immobility fear reactions of Japanese quail divergently selected for adrenocortical responsiveness to immobilization.
Tonic immobility responses were generally more pronounced in quail of the HS line than the LS line, and they were exaggerated in both lines after exposure to stress treatment, providing further support for the suggestion that selection for exaggerated or reduced adrenocortical responsiveness may have been accompanied by a concomitant and unconscious effect on underlying fearfulness.
Genetic Selection For Coping Style Predicts Stressor Susceptibility
The present data show that both stress paradigms induced line‐dependent physiological and neuroendocrine changes, but that the sensory contact stressor produced chronic stress symptoms in LAL mice only, which seems promising to analyse the role of genetic factors in the individual differences in stress‐related psychopathology.
