This article adopts a place-based approach to explore tiger atmospheres in the Sundarbans, a transboundary environmental commons and major climatic hotspot in the Ganges-Brahmaputra-Meghna delta of India and Bangladesh. We argue that affective intensities of greed ( lobh), fear ( bhaya), respect ( srodhya), trust ( biswas) and empathy ( karuna) sensed by the tiger subject contribute to novel theoretical as well as empirical insights into co-belonging and intersectional multispecies justice. We explore these animal atmospheres through multi-sited ethnographic research that include embodied observations, photographs, 31 in-depth interviews and focus groups with impoverished as well as racialised low-caste Hindus (Dalits/Scheduled Castes), Adivasis (Indigenous peoples) and Muslim forest-dwellers in India and Bangladesh. This attention to more-than-human geographies, animal atmospheres and subaltern stories situated in the Bengal delta unsettles macro-narratives of forest conservation and wildlife management that reduce animals to passive subjects or alternatively make them killable.
