The locals found the feathered bipedal creature, which seemed to have died a few days ago, near a remote village of Meshginshahr, IRNA reported on Sunday.
A team of officials of Iran's Environment Protection Organization (EPO) were dispatched to the region to investigate whether the reports were true.
One of the villagers has reportedly hidden the carcass and the EPO team is trying to find it. The team has managed to obtain a photo of the creature taken by one of the locals.
The team has also found evidence that confirmed the locals' claims the bird lived in a cave near the village.
