Territories for which the increase in the population number of the Peregrine Falcons has been confirmed

60% of the Peregrine Falcons breeding on the river cliffs
The share of nests of the Peregrine Falcon on the steppe rocks increased from 5 to 17%, the nests became more accessible

Clutches usually have 2–4 eggs, on average 3.6
Broods usually have 1–4 nestlings, on average 3.3
In the Volga-Ural region, the core of the Peregrine Falcon Population is concentrated in the Ural Mountains. These are low mountains

Nesting niche, used alternately by Eagle Owl and Peregrine Falcon
In such sink habitats breeding up to 30% of the Peregrine pairs near Ural Mountains
Nesting platforms were constructed in trees, at a height of 4-12 m from the ground, in the upper third of the crowns. Nesting trees were at a distance of 15 to 100 m from the original Peregrine nests.
At the time of replacement, chicks were 28 - 35 days old. On nesting platforms they spent from 3 to 12 days where they were fed by adults regularly. In total there were more than 50 feedings noted. All four broods (nine young) fledged successfully and demonstrated typical behavior for the peregrines of their age.
The main threats of Peregrine Falcon:
1. Electrocution
2. Illegal catching
Electrocution
