Testing the interspecific body size principle in ungulates: the smaller they come, the harder they groom

Tick removal grooming may be centrally regulated by an internal timing mechanism operating to remove ticks before they attach and engorge (programmed grooming model) and/or evoked by cutaneous stimulation from tick bites (stimulus-driven model). The programmed grooming model predicts that organismic and environmental factors that impact the cost–benefit ratio of grooming (e.g. body size and habitat) will influence the rate of tick removal grooming. The body size principle predicts that smaller-sized animals, because of their greater surface-to-mass ratio, should engage

The impact of immersive exhibit design on visitor behaviour and learning at Chester Zoo, UK

As extinction rates accelerate, zoos have evolved from places for public entertainment to centres of conservation, education and research. Zoo-based learning is inherently ‘free-choice’, meaning it is subject to visitors’ personal experiences, knowledge and agendas. Naturalistic, ‘immersive’ exhibits are commonplace in modern zoos and should provide the sense of discovery that maximises free-choice learning. Chester Zoo is developing ‘Grasslands’, a multi-species, immersive exhibit based on African savannahs, due to open in 2023. To assess the educational potential of Grasslands, this

Consistency of Captive Giraffe Behavior Under Two Different Management Regimes

Long-term animal behavior studies are sometimes conducted at a single site, leading to questions about whether effects are limited to animals in the same environment. Our ability to make general conclusions about behavior is improved when we can identify behaviors that are consistent across a range of environments. To extend Veasey and colleagues’ ([1996b] Anim Welf 5:139–153) study, I compared not only activity budgets but also social behaviour of an all-female group of giraffe at The Maryland Zoo in Baltimore

Enrichment Methods used for Giraffa camelopardalis & Gazella dama mhorr at The East Midland Zoological Society: Twycross Zoo

To provide a more stimulating captive environment and to illicit species-specific behaviours, a review of the enrichment techniques used for two browsing ruminants, (the giraffe (Giraffa camelopardalis) and the Mhorr gazelle (Gazella dama mhorr), held at Twycross Zoo was undertaken. It is well known that the majority of giraffe in captivity will develop some form of abnormal behaviour (EAZA, 2006) and hence enrichment protocols are vital in keeping animals occupied and stress-free.
