The marbled catPardofelismarmoratais a Near Threatened small felid. The cat’s presence in Nepal is based on an anecdote. A camera trap-based study to access diversity and abundance of terrestrial mammals in eastern Nepal accumulated 3,014 camera trap days and resulted in 5,176 photographs of 17 medium-large sized mammal species. Amongst them, a marbled cat was captured at a single camera trap station in January 2018. The camera trap-capturing the marbled cat was located in the secondary forest at an altitude of 2,750 m a.s.l., dominated by free-ranging cattle close to a permanent human settlement (1.4 km) and a temporary cattle herding camp (0.4 km). This is the first photographic evidence of a marbled cat in Nepal. In this survey, we also recorded three other felid species: common leopardPantherapardus, Asiatic golden-catCatopumatemminckiiand leopard catPrionailurusbengalensis. We recommend detailed year-round camera trap surveys in the mid-hills of eastern Nepal along with research on adaptation of the small felids to human-dominated areas and assessment of immediate threats for preparing sound conservation management plans of the marbled cat and its sympatric species. Initiation of conservation programmes engaging localdokpa(herders) is necessary.

The Red panda Ailurus fulgens is an Endangered small carnivore that occurs in Bhutan, India, Myanmar, Nepal and the People's Republic of China. Wild populations of Red pandas have declined by 50% over the last three generations as a result of habitat loss and fragmentation, hunting and poaching. In 1979 an international studbook was established for the species to monitor the demographically small and unstable population in human care. At that time the breeding results were poor. In 1985 a European Endangered Species Programme (EEP) was initiated and from then onwards the Red panda population started to grow as improved breeding techniques were utilized. As at 31 December 2019 there were 407 Red pandas: 177.228.2 (♂♂.♀♀.??) in the EEP housed at 182 institutions. The EEP developed in stages over four decades, from a small population of Red pandas with low breeding success and high mortality, to a popular breeding programme with high breeding success and direct links to in situ conservation. However, there are still challenges that need to be addressed, such as mean kinship and genetic diversity, climate change and its effects on juvenile mortality, and the welfare of individuals housed in long‐term bachelor groups. These issues are highlighted to encourage future research into the conservation of this species with some indications given of what zoos can do to find solutions to the most‐pressing challenges.

GPS collars are frequently used to study the (behavioural) ecology of species. However, such collars can cause behavioural changes and can have negative physiological effects on the individuals wearing them. A pilot study to obtain data on behavioural and physiological effects of GPS collars on the target species would therefore be recommended, especially when it concerns rare or endangered species. The red panda (Ailurus fulgens) is a small carnivore endemic to the mountains of Central Asia that is currently classified as endangered. There is a lack in knowledge on the species ecology which could be enhanced by a study using GPS-technology. As a pilot study, the two adult red pandas in Rotterdam Zoo were observed before and after fitting a GPS-collar, to determine possible behavioural effects of wearing a collar. Although the study did not take place under ideal circumstances, indications of both behavioural, e.g. increased shaking behaviour, and physical, e.g. abrasions, effects of the collar were found. Even though our results were only based on two individuals, our findings stress the need for pilot studies in controlled environments before GPS collars to ensure safety of the study species and validity of the collected data.

It is sometimes essential to have an animal in the hand to study some of their ecological and biological characteristics. However, capturing a solitary, cryptic, elusive arboreal species such as the red panda in the wild is challenging. We developed and successfully tested a protocol for tracking, trapping, immobilization, and handling of red pandas in the wild in eastern Nepal. We established a red panda sighting rate of 0.89 panda/day with a capture success rate of 0.6. We trapped and collared one animal in 3.7 days. On average, we took nearly 136 (range 50–317) min to capture an animal after spotting it. Further processing was completed in 38.5 (21–70) min. Before capture, we found it difficult to recognize the sex of the red panda and to differentiate sub-adults above six months from adults. However, body weight, body length, tail length, shoulder height, and chest girth can be used for diagnosis, as these attributes are smaller in sub-adults. Our method is a welfare-friendly way of trapping and handling wild red pandas. We report new morphometric data that could serve as a guide for field identification.

We report the first record of a Bengal Tiger, Panthera tigris tigris, in eastern Nepal in 2020 based on photographic evidence. We documented this evidence at 3,165 m a.s.l., which makes it the highest elevation record of a tiger in Nepal. We recorded this evidence in one of 46 trail cameras deployed for monitoring Red Pandas in the Panchthar-Ilam-Taplejung (PIT) area. The PIT area, which has non-protected status, borders India in the east. Our finding supports the importance of transboundary conservation, which will benefit local and flagship wildlife in the PIT area.

The red panda is listed as “endangered” in the IUCN Red List of Threatened Species, due to the rapid population decline. Improving our knowledge on the red panda biology and ethology is necessary to enhance its husbandry and breeding in zoos. Behavioural variety, intended as the presence of a wide array of species-specific behaviour, has been considered a positive welfare index in zoo-housed animals. The aim of this study was to describe the behaviour of two pairs of zoo-housed red pandas, one of them with an offspring, and to investigate the behavioural variability using the Behavioural Variety Index (BVI). Behavioural data from two zoo-living male–female pairs were collected. A continuous focal animal sampling method was used to collect individual and social behaviours of the two pairs. Forty-eight 30 min sessions per subject were carried out. For the BVI, a list of species-specific behaviours previously reported in the red panda was prepared and compared with the behavioural repertoire of the subjects of the study. First, species-specific behaviours were recorded, and no abnormal behaviour was reported. The percentages of time spent on different activities (e.g., routine behaviours, exploratory/territorial behaviours, consumption behaviours, locomotive behaviours, social behaviours, maternal behaviours) were similar to time budgets reported in the red panda, with routine behaviours (resting, comfort and vigilance) being the most performed in both pairs. Moreover, the BVI suggested that each red panda performed on average 73% of the behaviours described in previous literature on this species. In conclusion, studying the behavioural variety of red pandas in zoos can be a useful tool for assessing their welfare as well as improving our knowledge on the behavioural repertoire of a species that is difficult to observe in the wild.
