Well your question can be split into 3:
1. are there still Zoroastrians? Yes -- in India, Iran, the US, Canada and Australia with the largest community of 70,000 in India. They are in Kerman province in Iran
2. Are there zoroastrians in Iraq? I don't know -- I guess a few, not more than a couple of hundred, all among the Kurds (an Irani people)
3. Are these people the Yazidis Zoroastrians? Well, not quite. Some kind of syncretism.
Cloudmountain is correct. Yazidis are a Kurdish ethno-religious group. Their religion has a strong Islamic influence together with aspects of Zoroastrianism, and pagan practices & beliefs.
>>>”They are in Kerman province in Iran”<<<
In Iran, mostly in Kerman and Yazd provinces. Although you can find Zoroastrians in other Iranian provinces too. By the way, Yazd province of Iran is Not related to the term “Yazidis” or a Kurdish ethno-religious group called “Yazidis”.
