Wondering if he's just a variation on the IB theme.

What a handsome boy! Got to love the unusual white around his eye.

He probably has some Green Peafowl ancestry. Since many captive Indian Peafowl have some Green blood, it's not that unusual it just rarely shows up though.

The facial skin could look like that from being damaged or hybridization. Sometimes the opposite occurs in pure, inbred or composite (mixed from different forms) Green Peafowl where the dark facial skin and feathers around the eye divide the white areas .

He resembles the feral peafowl of Japan. These are over 90% Indian (Sri Lankan actually) Peafowl but have less than 10% Green Peafowl genes from various forms.
