Abstract Impacts and outcomes of using infra-red trail cameras on captive red panda (Ailurus fulgens) behaviour by Kathryn Bugler Introduction: Cryptic species are often studied using trail cameras in the wild. However, their use may cause some animals to be attracted or repelled by them, skewing presence/absence studies, abundance/population estimates and general behaviour patterns. Red panda are an elusive and rare species, found in only the Himalayan mountain range. A recent study observed red panda examining trail cameras on their trails in the wild. Understanding how they respond to trail cameras may influence how cameras are used to monitor them in the future. Aims: I assessed whether trail cameras affected captive red panda behaviour. I also determined time budgets and how they may differ with different observational methods. Methods: I used three zoo study sites, Auckland Zoo, Hamilton Zoo and Currumbin Wildlife Sanctuary. Auckland Zoo had a male and female pair with their three-month-old male offspring. Hamilton Zoo had an older male, female pair with their four-year-old female offspring. Currumbin Wildlife Sanctuary housed a single older male. A Kinopta Blackeye camera was set up on enclosure fencing to record continuously for the full study period. Study periods were split into three sections, with the first being labelled as before trail cameras, this just had the Blackeye camera. The middle third had trail cameras set up inside the enclosure and was called the during period. The last third of the trial (after trail cameras removed) had only the Blackeye setup, with trail cameras removed. During the entire study period, direct personal observations were also taken, noting typical significant factors, such as weather and temperature. Statistical analysis was carried out using R studio, with a mixture of chi-square, negative binomial GLMs, emmeans, pairwise comparisons and AIC tests. Graphs were created with Excel and R studio. Results: Sleeping was the most common behaviour, followed by locomotion, resting, eating and grooming. All other behaviours were less than 1% of all behaviours. The most active periods occurred ii in a crepuscular pattern, as with wild panda and in some cases, followed keeper timings. This led to the significant difference between zoo activity budgets. There was a significant difference in types of behaviours recorded with the two observational methods, showing that method does affect the type of data collected. Trail cameras affected behaviour at all zoos by changing the way red panda spent their time. Captive red panda were slightly more active with trail camera presence. Temperature also had a significant impact on length of behaviours. Red panda spent more time sleeping and resting at higher temperatures. Conclusions: As trail cameras changed the way red panda spent their time (in a captive setting), care should be taken for using trail cameras in the wild. While stress responses and obvious signs of avoiding areas with trail cameras did not occur, if behaviour is being monitored, then it is likely to be skewed by trail camera presence. Red panda were more active during trail camera presence, which might suggest an inflated abundance estimate if using trail cameras in the wild.

Acknowledgements I want to start by thanking my dog, Niya. For being my constant companion while reading, writing and analysing behaviour videos. Thank you for reminding me to take a break, enjoy the great outdoors and that midday naps and midnight snacks aren’t the end of the world. The biggest of thank yous to my supervisors, Adrian Paterson and James Ross. Thank you for dealing with my umming and arring over what to study, at the beginning, and allowing me to study my favourite animal. Thank you for being patient when it took me so long to process all the footage I gathered and for the help analysing it all. I hope we get to work together in the future. To Fiona Bellinger, Arneka de Vries and the rest of the admin team in the ecology department at Lincoln University. Thank you for helping me book accommodation, flights and everything else necessary for me to carry out my studies. Thank you to Lauren Booth and the carnivore team at Auckland Zoo, who were so accommodating and welcoming, while I studied your red panda. Thank you for having lunch with me every day and allowing me to meet Khela, Ramesh and baby Tashi. A true honour. To Jesse Golden, Cheridan Mathers and the keepers at Hamilton Zoo, thank you for having me and answering all of my constant questions about Taylor, Chito and Jamuna. It was a privilege to see and interact with Taylor and Chito, years after meeting them the first time (RIP). Jamuna and her floppy ear never failed to put a smile on my face, even when I sat watching them in stormy weather. Many thanks to Anthony Molyneux and the “Lost Valley” keepers at Currumbin Wildlife Sanctuary. You were life savers after my initial third zoo didn’t respond. Your insights and stories about your red panda were invaluable. I hope Pasang hasn’t eaten any more water dragons in my absence! In general, a major thank you to Auckland Zoo, Hamilton Zoo and Currumbin Wildlife Sanctuary for having me, and allowing me to film your red pandas. Thank you to my flat-mate and best friend, Caitlin. Bouncing ideas off each other has been a constant source of inspiration, even if I don’t understand what it is that you do. And lastly, thank you to my rowing squad for always providing the perfect outlet and for not asking, too often, how my thesis was going. iv Table of Contents Abstract ....................................................................................................................................... ii Dedication ................................................................................................................................... iv Acknowledgements ..................................................................................................................... iv Table of Contents ......................................................................................................................... v List of Tables .............................................................................................................................. vii List of Figures ............................................................................................................................ viii Chapter 1 Introduction ............................................................................................................ 1 1.1 Thesis structure .........................................................................................................................5 Chapter 2 Literature review ..................................................................................................... 6 2.1 Literature review .......................................................................................................................6 2.1.1 History .......................................................................................................................... 6 2.1.2 Taxonomy ..................................................................................................................... 6 2.1.3 Anatomy ....................................................................................................................... 9 2.1.4 Reproduction................................................................................................................ 9 2.1.5 Diet .............................................................................................................................12 2.1.6 Population and distribution .......................................................................................12 2.1.7 Habitat ........................................................................................................................13 2.1.8 Home range size .........................................................................................................14 2.1.9 Threats – dog attacks and diseases ............................................................................14 2.1.10 Threats- livestock .......................................................................................................15 2.1.11 Threats – anthropogenic effects ................................................................................15
