I saw a video on youtube and read about Yazidis:
The Yazidis are monotheists,believing in God as creator of the world, which he has placed under the care of seven holy beings or angels, the chief of whom is Melek Taus, the Peacock Angel. The Peacock Angel, as world-ruler, causes both good and bad to befall individuals, and this ambivalent character is reflected in myths of his own temporary fall from God's favor, before his remorseful tears extinguished the fires of his hellish prison and he was reconciled with God.
The purity of Earth, Air, Fire and Water is protected by a number of taboos, e.g. against spitting on earth, water or fire.
Their children are baptised at birth and circumcision is not required, but is practised by some due to regional customs.
Their temples have domes like we have in Hinduism.
My question: Is this peacock angel Kartikeya? Are they related to Hinduism in some way, probably migrated there? How come a peacock reached a deserted region?
