The precise identification of postural behavior plays a crucial role in evaluation of animal welfare and captive management. Deep learning technology has been widely used in automatic behavior recognition of wild and domestic fauna species...
After the loss of one of our breeding males and the export of loris offspring, in 2021 our off-show female loris was solitary. During this time, we noticed a number of changes in this female...
Enrichment devices are important tools to engage zoo-housed animals in species-specific natural behaviours, which is critical to ensure animal welfare. The gelada Theropithecus gelada has a unique graminivorous feeding ecology, yet there is minimal enrichment...
The re-release of golden lion tamarins (Leontopithecus rosalia), from zoos into the wild, is considered to be an ex situ conservation success story. However, zoo-born golden lion tamarins have lower survival rates than their wild-born...
This study aimed at evaluating the effects of unpredictability on behavioral and clinical aspects of Geoffroy's woolly monkey (Lagothrix cana cana) - a frugivorous Amazonian primate species - under human care. We studied seven individuals...
Research primates may undergo surgical procedures making effective pain management essential to ensure good animal welfare and unbiased scientific data. Adequate pain mitigation is dependent on whether veterinarians, technicians, researchers, and caregivers can recognize and...
Recent years have witnessed major advances in the ability of computerized systems to track the positions of animals as they move through large and unconstrained environments. These systems have so far been a great boon...
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...
Self-directed behavior, such as self-scratching (hereafter, scratching), occurs in several taxa across the animal kingdom, including nonhuman primates. There is substantial evidence that scratching is an indicator of anxiety-like emotions in a variety of nonhuman...
This traditional snack has a variety of options for NHP enrichment. From fruit to cereals, get creative with the “ants” and remember to consider different fillings for the celery log.
