“…It is therefore likely that the response of the hens to APC was directly relevant to the chicks' situation, rather than simply being a response to a peripheral feature of the air puff. The air puff was selected for the use as a putative stressor during APH and APC, and the behavioural and physiological changes occurring in response to APH indicate that it fulfilled its role, to the extent that it induced changes consistent with 'emotional stress' [18,19] and behavioural responses observed in negatively valenced situations [20].…”

“…a positive or negative response), as would be necessary to label it as 'emotional' and thereby 'empathic'. Some of the physiological and behavioural changes discussed have previously been used as signs of an emotional response in animals [19,20], and we have shown independently that adult hens will work to avoid environments associated with some of the behavioural changes that were observed during the APC and APH conditions in this experiment [16]. However, direct evidence would be required to conclude that the hens' response to APC was negative, as it might simply indicate a non-valenced, and thus nonemotional, reaction (akin, for example, to 'arousal', 'interest' or 'heightened attention') to the behaviour of their chicks.…”

Avian maternal response to chick distress

The extent to which an animal is affected by the pain or distress of a conspecific will depend on its capacity for empathy. Empathy most probably evolved to facilitate parental care, so the current study assessed whether birds responded to an aversive stimulus directed at their chicks. Domestic hens were exposed to two replicates of the following conditions in a counterbalanced order: control (C; hen and chicks undisturbed), air puff to chicks (APC; air puff directed at chicks at 30 s intervals), air puff to hen (APH; air puff directed at hen at 30 s intervals) and control with noise (CN; noise of air puff at 30 s intervals). During each test, the hens' behaviour and physiology were measured throughout a 10 min pre-treatment and a 10 min treatment period. Hens responded to APH and APC treatments with increased alertness, decreased preening behaviour and a reduction in eye temperature. No such changes occurred during any control period. Increased heart rate and maternal vocalization occurred exclusively during the APC treatment, even though chicks produced few distress vocalizations. The pronounced and specific reaction observed indicates that adult female birds possess at least one of the essential underpinning attributes of empathy.

“…SIH typically raises core body temperature by 0.5-1.5 °C within 10-15 min of an acute stressor 10 . It is a relatively well documented phenomenon that a commonly applied experimental stressor of catching and handling an animal can raise core body temperature in a range of mammal and bird species [11][12][13][14][15][16][17] . Importantly, SIH correlates with other established indicators of stress, such as heart rate 18 , glucocorticoid levels 19 and behavior 20,21 .…”

Stress, a central concept in biology, describes a suite of emergency responses to challenges. Among other responses, stress leads to a change in blood flow that results in a net influx of blood to key organs and an increase in core temperature. This stress-induced hyperthermia is used to assess stress. However, measuring core temperature is invasive. As blood flow is redirected to the core, the periphery of the body can cool. This paper describes a protocol where peripheral body temperature is measured non-invasively in wild blue tits (Cyanistes caeruleus) using infrared thermography. In the field we created a set-up bringing the birds to an ideal position in front of the camera by using a baited box. The camera takes a short thermal video recording of the undisturbed bird before applying a mild stressor (closing the box and therefore capturing the bird), and the bird's response to being trapped is recorded. The bare skin of the eye-region is the warmest area in the image. This allows an automated extraction of the maximum eye-region temperature from each image frame, followed by further steps of manual data filtering removing the most common sources of errors (motion blur, blinking). This protocol provides a time series of eye-region temperature with a fine temporal resolution that allows us to study the dynamics of the stress response non-invasively. Further work needs to demonstrate the usefulness of the method to assess stress, for instance to investigate whether eye-region temperature response is proportional to the strength of the stressor. If this can be confirmed, it will provide a valuable alternative method of stress assessment in animals and will be useful to a wide range of researchers from ecologists, conservation biologists, physiologists to animal welfare researchers.

“…Before and after the defeat we measured a number of physiological and behavioral parameters known to be affected by psychosocial stress in rodents (body temperature, social behavior, activity) and by handling stress in birds [4]. It was not possible to measure cardiovascular parameters, but breath rate was assumed to respond similarly to heart rate since both are part of the adrenergic stress response.…”

Effect of social defeat in a territorial bird (Parus major) selected for different coping styles Carere, C; Welink, D; Drent, Piet J.; Koolhaas, Jaap M.; Groothuis, Ton Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim.Downloaded from the University of Groningen/UMCG research database (Pure): http://www.rug.nl/research/portal. For technical reasons the number of authors shown on this cover page is limited to 10 maximum. AbstractWe addressed the questions (i) whether a social defeat triggers similar autonomic and behavioral responses in birds as is known from mammals and (ii) whether individuals that differ in coping style differ in their reaction to a social defeat. Adult captive male great tits (Parus major) from either of two different selection lines for coping style were used to test the effect of social defeat by an aggressive resident male conspecific on subsequent social and nonsocial behaviour, body temperature, breath rate and body mass. These parameters were measured 1 day before (baseline), immediately after and at Days 1 to 3 and 6 after the social interaction took place (Day 0). Social defeat decreased social exploration and increased body temperature substantially for at least 1 day in all birds. Breath rate and body mass were not affected. Birds belonging to the more aggressive and bolder line showed impairment in activity immediately after the social defeat. This is to our knowledge the first report showing that psychosocial stress in birds can have a similar impact as in rodents, but with a shorter recovery time. This might be due to species-specific differences in sensitivity to social stress, or to differences in the way social stress was induced. D
