Cranes are iconic migratory birds that face welfare threats from habitat loss, hunting, powerline collisions, and the disruption of their complex social bonds during long migrations.
Cranes face welfare challenges across their entire annual cycle. During migration they must navigate increasingly fragmented wetland stopover sites that offer insufficient food and rest. Hunting pressure along migratory routes — legal in some countries, illegal in others — causes direct mortality and chronic disturbance. Powerline strikes cause traumatic injury and death; surviving birds with wing injuries may be unable to continue migration. The disruption of pair bonds — whether through hunting, collision, or capture — causes measurable behavioural distress in highly social birds with long memories. Wetland drainage for agriculture eliminates critical staging and wintering habitat. Climate change is shifting the timing and location of suitable habitat, creating mismatches between crane migration and available resources.
