Ospreys are Schedule 1 protected species in the UK, and disturbance of nesting birds is a serious crime. Protecting nest sites is critical to the recovering population.
Disturbance at osprey nests causes nest abandonment, chick exposure to weather, and predation of eggs and chicks. Human presence near active nests causes chronic stress to incubating birds. Protecting nest sites from unauthorised access during the breeding season is essential to the welfare of nesting birds.
