Tortoise Husbandry and Welfare

Keeping captive tortoises healthy and well is a significant challenge. Because they are ectotherms, these reptiles are totally dependent upon external sources to maintain body temperature and therefore metabolic function. Their physical environment is vital for them to remain healthy,...

A case of thanatosis in domestic sheep

Thanatosis (feigning death, defensive tonic immobility) is a widespread anti-predator behavioural strategy in animals. Animals that have evolved this behaviour react to physical contact with the predator by displaying a persistent tonic immobility that makes them look like dead prey....

Horse vision through two lenses: Tinbergen’s Four Questions and the Five Domains

To improve human–horse interactions and reduce the risk of injury, it is essential to adopt an equi-centric perspective that prioritizes how horses perceive their environment. This review focuses on the equine visual system, both because it is the most studied...

Sleep preferences in CD1 mice in a laboratory environment

This study investigates the preferences of CD1 mice in a lab environment for various sleeping enrichment options within their cages. Understanding the environmental factors that influence sleep behaviour is crucial for enhancing animal welfare in laboratory settings. We assessed two...

Dance behaviour in cockatoos: Implications for cognitive processes and welfare

Parrots (Aves, Psittaciformes) in captivity have been reported to show dance behaviour in response to music, which may involve complex cognitive processes including imitation, vocal learning and entrainment. Dance behaviour in parrots may be indicative of a positive welfare state...

Effects of flight restraint and housing conditions on feather corticosterone in white storks under human care

Flight is part of the natural behaviours of most bird species, and as a consequence, flight restraint in zoos, even for those species that are primarily ground-dwelling, encounters increasing animal welfare concerns. While previous studies on greater flamingos (Phoenicopterus roseus)...

Affective responses and behavioral strategies to social fusion events in zoo-housed bonobos

Species with fission-fusion dynamics may face heightened social tension during fusion events due to relationship insecurity and competition over resources. Affective consequences of such events are important determinants for behavioral responses, yet remain poorly understood. To evaluate the affective consequences...

Evidence of play behavior in captive California two-spot octopuses, Octopus bimaculoides

Play is considered to be an essential part of development that supports learning, memory, and the development of flexible behavioral strategies. It may also serve as an informative factor in assessing an animal’s welfare state and in improving care and...

Chew sticks, do mice really care?

There are various chewing enrichments on the market for small rodents. In this study we focused on comparing two types, T-Brick and Aspen to see which product enabled more natural chewing behaviours in several strains of mice. A rack of...

Behavioral and spatial analysis of a Symphalangus syndactylus pair in a controlled environment

For the effective management of captive animals, monitoring their behavior and interactions within the exhibit is essential. This approach provides insights into their welfare and helps identify behavioral differences compared to conspecifics in the wild. This ex situ study aimed...
