Sarus cranes are the world's tallest flying birds, with welfare and conservation needs centred on seasonal wetland protection in India and Queensland, Australia.
Sarus cranes form lifelong pair bonds with documented strong social attachment. Disruption of pair bonds through death or physical separation causes observable distress. Nesting cranes disturbed at nest sites abandon eggs or chicks causing reproductive welfare failure. Exposure to organophosphate pesticides through foraging in treated fields causes poisoning deaths. The cognitive complexity and strong social bonds of cranes mean habitat loss affects welfare beyond nutrition, disrupting the social and spatial knowledge accumulated over decades.
