Desperate attempt to protect saker falcons known as the feathery treasure of Siberia.
Ecologists from several countries lost battle to poachers who caught an endangered dark-feathered bird.
In separate case, members of a 'bird mafia' illegally snaring and exporting Red Book hawks and falcons to Middle East were detained in Buryatia.
Earlier reports suggested organised gangs seek to sell gyrfalcons on the black market for as much as $50,000 each.
