Cranes undertake some of the world's most challenging migrations, facing hazards from hunting to power line collisions and habitat loss along flyways.
Migration is inherently taxing, requiring immense energy reserves and navigation precision. Cranes that encounter depleted stopover wetlands face starvation during critical refuelling phases. Hunting pressure at key staging sites elevates stress hormones and disrupts traditional routes. Surviving cranes that witness flock members die at power lines or from poisoning experience what behavioural ecologists describe as social disturbance responses.
