Aberrant plumaged birds

My interest in odd plumages and colour mutations in birds was given a huge boost recently. I had a meeting with Hein van Grouw, curator of birds at Tring natural history museam, and a leader in this field. I learned a lot and he gave me a couple of the papers he had written. (Links below). A very interesting read.
