The influence of thermoregulatory demand on contact crèching behaviour in Adélie Penguin chicks

(1) We tested the hypothesis that contact behaviour in Adélie Penguin (Pygoscelis adeliae) chicks of crèching age is strongly influenced by thermoregulatory demand. (2) Estimated thermoregulatory costs (% minimal metabolic rate) for early crèche stage (1 kg) chicks were much higher (13.4–121.0%) than for late crèche (3 kg) chicks (0–45.1%). The incidence of contact behaviour […]

Radiographic analysis of the development of the pelvic limb of captive-reared cranes (Grus spp.)

Abstract 10.1002/(SICI)1098-2361(1996)15:23.3.CO;2-P For captive-reared cranes, pelvic limb abnormalities in chicks have been identified as significant morbidity/mortality factors. An important component of the diagnosis of limb abnormalities is the understanding of the normal limb. This study was undertaken to describe the normal, radiographic development of the femur, tibiotarsus, tarsometatarsus, and fibula of the whooping crane (Grus […]

Application of video recording technology to improve husbandry and reproduction in the carmine bee-eater (Merops n. nubicus)

Incorporating technology with research is becoming increasingly important to enhance animal welfare in zoological settings. Video technology is used in the management of avian populations to facilitate efficient information collection on aspects of avian reproduction that are impractical or impossible to obtain through direct observation. Disney’s Animal Kingdom® maintains a successful breeding colony of Northern […]
