“…25,26,29,31,36 During the course of treatment, the chemotherapy was suspected to have suppressed the bird's testosterone levels, thereby preventing it from developing the weight gain and vocalization behaviors typical of the breeding season. 5,6 Cyclophosphamide has been shown to have a negative effect on testis and epididymal weight, as well as to decrease serum luteinizing hormone and testosterone levels in mice. 37 Furthermore, a reversible decrease in spermatogenesis and sperm motility has been documented in both mice and people undergoing treatment with cyclophosphamide.…”

A 22-year-old, wild-caught male kori bustard (Ardeotis kori) developed a large, slow-growing subcutaneous mass over the keel. The mass was surgically debulked and histopathologically described as a myxosarcoma. Surgical dehiscence and concurrent local tumor regrowth, with no evidence of metastasis, occurred over the subsequent 3 months, necessitating 2 additional surgical procedures to close the wound. At 19 weeks after the initial procedure, a second debulking surgical procedure was performed, at which time carboplatin-impregnated matrix beads were placed in the lesion. Moderate local tumor regrowth was clinically appreciable 4 weeks after surgery, at which time an oral metronomic chemotherapeutic protocol consisting of daily cyclophosphamide (10 mg/m(2)) and meloxicam (0.1 mg/kg) was initiated. Four months later, the tumor was no longer palpable. While oral therapy was discontinued during the breeding season, mass regrowth was observed, and the mass was surgically debulked before reinitiating oral chemotherapy. Treatment was extended for over 1 year with no hematologic evaluation or serum biochemical abnormalities, and the bird otherwise remained clinically healthy. To our knowledge, this is the first report of a myxosarcoma in a bustard species and the first report of successful clinical application of metronomic chemotherapy in an avian species.

“…The easiest lands to convert are those with already open canopies and sparse vegetation, which are the same as those shown to be used by Kori Bustards. Kori Bustards are known to have low tolerance for human activity and would most likely avoid areas of agriculture and human development instead of adapting to the change in habitat (Herremans 1998, Osborne and Osborne 2001, Lichtenberg and Hallager 2008.…”

“…The species is considered near threatened on the IUCN Red List (BirdLife International 2016) and the South African red data book classifies Kori Bustards as vulnerable (Brooke 1984). Kori Bustards' low tolerance of human activity and their low reproduction rates during dry years have compounded these declining population trends (Herremans 1998, Osborne and Osborne 2001, Lichtenberg and Hallager 2008. Other threats to the species include collisions with powerlines (Martin andShaw 2010, Shaw et al 2010), poaching, and predation (Senyatso et al 2013).…”

ABSTRACT. Conservation planning and decision making for species of concern requires precise information on abundance and habitat associations. We conducted transect surveys throughout the Northern Tuli Game Reserve, Botswana during June-July 2014 and MayJuly 2015 to estimate the occupancy and abundance of Kori Bustards (Ardeotis kori). The probability of occupancy of Kori Bustards was greater in areas with tree canopy cover ≤ 50% (ψ2014 = 0.37, SE ± 0.09; ψ2015 = 0.39, SE ± 0.06) when compared with areas with tree canopy cover > 50% (ψ2014 = 0.00, SE ± 0.00; ψ2015 = 0.00, SE ± 0.00). Densities of Kori Bustards ranged from 0.03-5.02 individuals/km² at our study sites. They showed annual variation, and densities were highest in areas where vegetation was classified as sparse or bare soil. Areas at low (≤ 540 m above sea level) and high (≥ 540 m above sea level) elevations at our study sites also exhibited differences in density of Kori Bustards but elevational differences varied among years. Areas categorized as both sparse vegetation and higher elevation had the highest estimated densities in 2014 with 5.02 individuals/km². Areas categorized as sparse vegetation and lower elevation had the highest densities in 2015 with 2.20 individuals/km². Our study demonstrates that areas of sparse vegetation and open canopy areas are important to Kori Bustards. However, open canopy areas outside of reserves may be at risk of conversion to row crop and other forms of agriculture as human populations and demands for food increase. Habitat-specific information will be useful for future studies to identify risks during landscape conservation planning within the range of the Kori Bustard. L'abondance de l'Outarde kori (Ardeotis kori) varie selon la végétation et l'élévation dans la réserve de chasse de Northern Tuli, Botswana RÉSUMÉ. La planification de la conservation et la prise de décisions pour les espèces préoccupantes requièrent des données précises sur leur abondance et leurs associations avec l'habitat. Nous avons effectué des relevés par transects dans la réserve de chasse de Northern Tuli, au Botswana, en juin-juillet 2014 et mai-juillet 2015, afin de déterminer l'occurrence et la densité d'Outardes kori (Ardeotis kori). La probabilité d'occurrence des outardes était supérieure dans les endroits où la voûte forestière couvrait ≤ 50 % (ψ2014 = 0,37, écart-type ± 0,09; ψ2015 = 0,39, écart-type ± 0,06) comparativement aux endroits où la voûte couvrait > 50 % (ψ2014 = 0,00, écart-type ± 0,00; ψ2015 = 0,00, écart-type ± 0,00). Les densités de cette outarde s'élevaient de 0,03 à 5,02 individus/km² dans nos sites d'étude. Les densités montraient des variations annuelles et étaient plus élevées dans les endroits où la végétation était classée comme « éparse » ou « sol nu ». Les densités ont aussi différé selon les endroits de basse (≤ 540 m au-dessus du niveau de la mer) ou de haute (≥ 540 m ASL) élévation dans nos sites d'étude, et ces différences ont varié entre les années. Les endroits classés à la fois comme de végétation ép...

“…[24,25], the behaviours reported in this paper were compiled from several sources. In order to assess as many of the behaviours shown by giraffes as possible, numerous peer-reviewed articles, dissertations and theses, and other publications (Appendix), focussing on descriptions of giraffe behaviour or at least partly addressing the topic, were reviewed for behavioural descriptions and definitions e.g.…”

BackgroundNumerous factors like continuous habitat reduction or fragmentation for free-ranging giraffes (Giraffa camelopardalis) as well as e.g. suboptimal housing conditions for animals in captivity might lead to behavioural alterations as part of the overall adaptation process to the changing living conditions. In order to facilitate current and future studies on giraffe behaviour, a comprehensive ethogram was compiled based on existing literature, as well as observations on giraffes in the wild (Hwange National Park, Zimbabwe; Entabeni Game Reserve, South Africa), and in captivity (National Zoological Gardens of South Africa, Pretoria).FindingsThe resulting ethogram lists 65 different behavioural patterns, which were described and grouped into seven categories: General activities, Abnormal repetitive behaviours, General interactions, Bull-Cow behaviour, Bull-Bull behaviour, Cow-Bull behaviour, Maternal behaviours, and Interactions by calves. The behaviours were further described regarding a presumed purpose, particularly with respect to social interactions and sexual behaviour. Contradictory descriptions from previous studies were considered and discussed in comparison with our own observations.ConclusionsThis ethogram provides a basis for current and future studies by suggesting a terminology which can be used for harmonizing behavioural observations, thus helping to facilitate comparability of future results. Subsequently, a better understanding of the behavioural ecology of giraffes in the wild as well as in captivity could aid future conservation efforts.
