“…The use of video recording allows for more comprehensive, 24/7 welfare monitoring (Brando & Buchanan-Smith, 2018), and is also useful for staff education and identification of rare behaviors. Furthermore, video footage can be augmented to allow for thermal imaging data to be recorded (Ross et al, 2021). Scoring behavioral data from video can be time-consuming, although automated tools for coding video footage are being developed that can expedite the coding process (Labuguen et al, 2021).…”

Across captive settings, nonhuman primates may develop an array of abnormal behaviors including stereotypic and self-injurious behavior. Abnormal behavior can indicate a state of poor welfare, since it is often associated with a suboptimal environment. However, this may not always be the case as some behaviors can develop independently of any psychological distress, be triggered in environments known to promote welfare, and be part of an animal's coping mechanism. Furthermore, not all animals develop abnormal behavior, which has led researchers to assess risk factors that differentiate individuals in the display of these behaviors. Intrinsic risk factors that have been identified include the animal's species and genetics, age, sex, temperament, and clinical condition, while environmental risk factors include variables such as the animal's rearing, housing condition, husbandry procedures, and research experiences. To identify specific triggers and at-risk animals, the expression of abnormal behavior in captive nonhuman primates should be routinely addressed in a consistent manner by appropriately trained staff. Which behaviors to assess, what assessment methods to use, which primates to monitor, and the aims of data collection should all be identified before proceeding to an intervention and/or treatment. This article provides guidance for this process, by presenting an overview of known triggers and risk factors that should be considered, steps to design a comprehensive evaluation plan, and strategies that might be used for prevention or treatment. It also outlines the tools and processes for assessing and evaluating behavior in an appendix. This process will lead to a better understanding of abnormal behavior in captive primate colonies and ultimately to improved welfare.

“…Results showed that IRT could aid in the early detection of a poor blood supply to the graft based on the stability of the vascularization of the transplanted skin. Recently, IRT has begun to be used in a field of research where emotional states derived from various stimuli have been found to correlate with thermal responses, especially in primates like rhesus monkeys ( Macaca mulatta ) [ 32 ], gorillas [ 33 ] and chimpanzees [ 34 ].…”

Promoting animal welfare in wildlife species under human care requires the implementation of techniques for continuously monitoring their health. Infrared thermography is a non-invasive tool that uses the radiation emitted from the skin of animals to assess their thermal state. However, there are no established thermal windows in wildlife species because factors such as the thickness or color of the skin, type/length of coat, or presence of fur can influence the readings taken to obtain objective, sensitive values. Therefore, this review aims to discuss the usefulness and application of the ocular, nasal, thoracic, abdominal, and podal anatomical regions as thermal windows for evaluating zoo animals' thermal response and health status. A literature search of the Web of Science, Science Direct, and PubMed databases was performed to identify relevant studies that used IRT with wild species as a complementary diagnostic tool. Implementing IRT in zoos or conservation centers could also serve as a method for determining and monitoring optimal habitat designs to meet the needs of specific animals. In addition, we analyze the limitations of using IRT with various wildlife species under human care to understand better the differences among animals and the factors that must be considered when using infrared thermography.

“…Thermal (infrared) [54] worked with thermal (infrared) imaging in a sanctuary setting where unrestrained chimpanzees were able to move freely around their enclosures. This was coupled with an evaluation of pairing information with long-term behavioural data for a multifactor welfare monitoring system.…”

Focusing on zoo environments, we conducted a literature review investigating the use of non-invasive technologies designed for monitoring the behaviour and welfare of animals. The research question asks: What technologies or monitoring methods have been able to capture information on behaviours and needs of animals in zoo, sanctuary, domestic or agricultural environments? From the initial literature review, we determined progressive zoos, research labs, institutions and companies and identified monitoring technologies developed to improve animal welfare. We then emailed out a concise survey to those zoos to gauge what monitoring technologies they were using and asked them to identify where systems and their deployment could be improved. We highlight advances and developments identified in the literature, to underline current and future monitoring needs of zoo environments. We contribute to the research field by mapping these sought-after changes against the most relevant identified monitoring technologies distinguished in the literature search
