Peregrine Falcons Nesting

We have a pair of Peregrines nesting in a tall tree in woods which overlook our back garden. Recently I discovered a dead peregrine chick at the bottom of the tree, which was being predated by Magpies. The Peregrines are obviously settled in the tree despite being harassed occasionally by Crows who also nest within the woods. Do I need to inform any group of their presence at this time?, having regard for the possible intrusion of unscrupulous individuals.
