Summary – We found that king cobras use very large areas compared to other snakes. Only a couple of species come close, Drymarchon couperi (Hyslop et al. 2016) and Python bivittatus (introduced population; Hart et al 2015). Our Thai kings did not cover areas as large those tracked in India’s Western Ghats. Perhaps more importantly we show that kings will not remain restricted to protected forested areas, and that breeding season may present a time of heighten movements meaning greater contact with human threats.

Future directions – The tracking of king cobras in Thailand was difficult and as a result the data was not as well-structured and regimented as would be ideal. This prevented more sophisticated analysis. Currently, using the knowledge gained during this study, we are continuing to track king cobras aiming to produce a data-set that will be able to tease out some more nuanced information about their movements and habitat usage. Check out Silva et al. (2018) for an idea of future directions.
