what provisions are in place to protect white-tailed eagles and their nests.

Under the Wildlife and Countryside Act 1981, birds of prey, including white-tailed eagles, are protected. The provisions of the Act make it an offence if a person recklessly or intentionally kills, injures or takes a bird of prey.
It is also an offence under the Wildlife and Countryside Act to: take, damage, destroy or otherwise interfere with a bird of prey nest, including white-tailed eagle, whether in use or being built; obstruct or prevent a bird of prey, including white-tailed eagle, from using its nest; take or destroy the egg of a bird of prey, including white-tailed eagle; intentionally or recklessly disturb a bird of prey, including white-tailed eagle while it is in a nest or is building a nest, or is on, in or near a nest containing eggs or young; and intentionally or recklessly disturb the dependent young of a bird of prey, including white-tailed eagle.

White-tailed eagles are also listed on Schedules A1 and 1A of the Wildlife and Countryside Act 1981. The Wildlife and Countryside Act 1981 (Variation of Schedules A1 and 1A (Scotland) Order 2013) came into force on 18th March 2013 and added golden eagle to Schedule A1 and 1A of the Wildlife and Countryside Act 1981 and hen harrier and red kite to Schedule 1A only. Schedule A1 of the 1981 Act lists bird species whose nests are protected at all times from disturbance, including outwith the breeding season and Schedule 1A of the 1981 Act lists those bird species which are protected from harassment.
