Common cranes have recolonised the UK and now overwinter in significant numbers. Their welfare at roost and feeding sites is affected by disturbance, wetland management and agricultural practice.
Crane welfare at UK roost sites is primarily affected by disturbance - whether from birdwatchers approaching too close, wildfowlers, or agricultural operations near roost sites. Cranes that flush repeatedly from roost sites burn energy reserves in winter when fat stores are critical for survival. A bird disturbed nightly from its roost site may enter spring in poorer condition than one that roosted undisturbed. The high visibility of cranes makes them magnets for wildlife photographers, who must balance enjoyment against welfare impact. Maintaining 200-300 metre buffers around roost sites during winter is the responsible approach.
