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 carmine bee-eaters.

Reproductive and parental behavior in Taveta golden weavers (Ploceus castaneiceps).

Taveta golden weavers are popular in zoos, but little has been published on their reproduction, social behavior, or other aspects of their management. At Disney's Animal Kingdom® , we have had great success with our breeding program and house a large flock in our mixed-species walk-through Africa aviary and smaller groups in the off-exhibit Avian Research Center. We conducted observations on both groups in order to document behavioral differences between the groups living under differing management conditions.

Identifying parentage using molecular markers: improving accuracy of studbook records for a captive flock of marabou storks (Leptoptilos crumeniferus).

Extra-pair copulations (EPCs) leading to extra-pair fertilization (EPF) are common in avian mating systems, despite the prevalence of observed social monogamy in many species. Colonially breeding birds are interesting species to investigate the prevalence of EPCs and EPF because they show nesting habits including close proximity of nest sites and sexual partners, which are proposed to promote alternative reproductive tactics. Endemic to Africa, the colonial marabou stork (Leptoptilos crumeniferus) is one of the most commonly held avian species in North American zoos.

Attempted integration of multiple species of turaco into a mixed-species aviary.

Mixed-species exhibits offer a variety of benefits but can be challenging to maintain due to difficulty in managing interspecific interactions. This is particularly true when little has been documented on the behavior of the species being mixed. This was the case when we attempted to house three species of turaco (family: Musophagidae) together with other species in a walk-through aviary.

Hand-rearing and sex determination tool for the Taveta golden weaver (Ploceus castaneiceps).

Improvements in the ability to hand-rear birds in captivity have aided zoological institutions in the sustainable management of these species, and have provided opportunities to examine their physical growth in varying conditions. Monitoring the weight gain and development of chicks is an important aspect of developing a hand-rearing protocol. In this paper we provide the institutional history for a colonial species of passerine, the Taveta golden weaver, at Disney's Animal Kingdom®, in order to demonstrate the methods of establishing a successful breeding program which largely incorporates hand-rearing in management of the population.

Use of novel nest boxes by carmine bee-eaters (Merops nubicus) in captivity.

Carmine bee-eaters make attractive additions to zoo aviaries but breeding programs have had challenges and limited success. The objectives of this study were to document nesting behavior of Carmine bee-eaters in a captive setting and compare reproductive success between a novel nest box (plastic, 17 x 30 x 22 cm) and a PVC pipe model used previously (30 cm long, 8 cm in diameter). Three bee-eater pairs were given access to seven nest chambers (six novel boxes, one PVC model).
