Bulgarian Vulture detained for spying and became hostage to the Yemeni Army.
According to Ivelin Ivanov, the army confiscated the bird in suspicion that the vulture is a spy because they think the transmitter is a spy device. After they sent a letter, Yemen Embassy in Bulgaria managed to convince the commander of the army where the bird is, and he agreed to return the transmitter and the bird. After lengthy diplomatic negotiations, the bird finally released.
The vulture is a scavenging bird of prey. The two types of vultures are the New World vultures, including the Californian and Andean condors, and the Old World vultures, including the birds that are seen scavenging on carcasses of dead animals on an African plain.
The vulture has been vacationing in the Arab Peninsula since November 2018. The young bird has been wing tagged and ringed in Kresna Gorge, and is being followed since then by GPS/GSM transmitter.
