I had a farm close to my place that had peacocks. They were great to get turkeys gobbling when they scream. They never interfered for years, but all of a sudden there was one bird that loved my calls. The first time I saw him, I heard a weird noise that sounded like a nose "toot". Then he screamed. LOUDLY!!! Next thing I know he comes strolling in. He ended up visiting me several times that year. The next year they all stayed on their own farm.
