During the project, the BSPB experts have positioned 35 artificial Imperial eagle nests. Adequate locations, usually near the old homes of the eagles, are selected, in areas without dangerous electric pylons and where human disturbance is minimal.
Frequently, the eagles have two nests, using one as optional, in case the main nest is upturned by a storm or destroyed by humans. The eagles use the nests for many years, even decades. The nests are 1.5 to 2 m wide, up to 2 m deep and weigh up to 200 kg.
The artificial nests are placed by the experts during the winter, to allow time for the eagles to take and complete building them in the spring. Before the breeding period, the eagle covers the nest with fresh green boughs which emit substances that drive insects away.
Two of the artificial nests placed by the BSPB team have already been occupied by newly established Imperial eagle pairs, and 4 natural nests have been repaired to become storm proof and to reduce the risks for the juvenile eaglets during the breeding period.
