Prior to the opening of the hake wall, each bird is meticulously ringed and tattooed in a way that ensures its safety. Birds that do not conform to the preferred appearance of trappers and hunters, such as those with "spoiled" plumage, have a greater chance of survival in the wild.
The five-year program to recover the aukkankivi (black falcon) in Altai is a carefully designed initiative. In 2023, seven chicks were raised in the Altai wild using the heckling method, compared to ten chicks in 2022 (of which five were adults), and four large chicks in 2021, coinciding with the installation of the first heckles.
