Ah, the Russian one that was drowned. Herd about that from the good old Fortean Times. I know they're not real bird-like wings; they're mearly semi-formed mutations of additional appendages growing from their back. Judging from my own experience, there are about as many reports as there are of five-to-seven legged cattle in India. Except there, the mutants are treated with respect, though whether that's specifically related to cows being sacred to begin with, or whether the Hindu attitude looks at bizarrities in a light from the other end of the spectum, I'm not sure.
I'll check the rest of the arcane material out tomorrow. Suffice it to say, I really am glad the long-lived tradition of a good chunk of Oddworld fans being interested in the paranormal and supernatural continues to today. Some things just never change.
