Серая куропатка — Perdix perdix.

This striking image by photographer Sumnikov Aleksey captures a grey partridge (Perdix perdix) in its natural environment. With its mottled brown and white feathers blending seamlessly into the green grassland, the bird exudes both beauty and camouflage. Its upright posture and open beak suggest it may be calling or reacting to its surroundings. A perfect example of European wildlife photography that highlights the charm and resilience of this ground-dwelling species in their native habitat.
