Ospreys are naturally recolonising England after extinction, with conservation sites protecting nests and tracking welfare of this iconic fish-hunting raptor as it re-establishes.
Osprey welfare challenges include nest disturbance during the sensitive incubation period, electrocution on power lines during migration, and food availability in both breeding and wintering grounds. Camera monitoring enables rapid response to welfare emergencies such as nest collapse or chick illness. Migration satellite tracking has revealed that some individuals make non-stop flights of over 4,000 km, a remarkable physiological feat that can go wrong in extreme weather.
