*Viewing the rare through public lenses: insights into dead calf carrying and other thanatological responses in Asian elephants using YouTube videos* *Sanjeeta Sharma Pokharel, Nachiketha Sharma & Raman SukumarThe Royal Society PublishingMay 18, 2022 Abstract* Documenting the behavioural repertoire of an animal species is important for understanding that species' natural history. Many behaviours such as mating, parturition and death may be observed only rarely in the wild due to the low frequency of occurrence, short duration and the species' elusiveness. Opportunistic documentation of rare behaviours is therefore valuable for deciphering the behavioural complexity in a species. In this context, digital platforms may serve as useful data sources for studying rare behaviours in animals. Using videos uploaded on YouTube, we document and construct a tentative repertoire of thanatological responses (death-related behaviours) in Asian elephants (Elephas maximus). The most frequently observed thanatological responses included postural changes, guarding/keeping vigil, touching, investigating the carcass, epimeletic behaviours and vocalizations. We also describe some infrequently observed behaviours, including carrying dead calves by adult females, re-assurance-like behaviours and attempts to support dying or dead conspecifics, some of which were only known anecdotally in Asian elephants. Our observations indicate the significance of open-source video data on digital platforms for gaining insights into rarely observed behaviours and support the accumulating evidence for higher cognitive abilities of Asian elephants in the context of comparative thanatology. *FULL PAPER PDF LINKhttps://drive.google.com/file/d/1FJ-Tk7KoLUG4nfM9681WGGz7NIAdtCqm/view?usp=sharing <https://drive.google.com/file/d/1FJ-Tk7KoLUG4nfM9681WGGz7NIAdtCqm/view?usp=sharing>FULL PAPER WEB LINKhttps://royalsocietypublishing.org/doi/full/10.1098/rsos.211740 <https://royalsocietypublishing.org/doi/full/10.1098/rsos.211740>*
