The unusual blackbird has taken up residence in the country park for the last four years. This unusual blackbird is attracting bird watchers to a Nottinghamshire country park. Leucistic birds are often very susceptible to predators, since of their bright white plumage. So the park's managers are urging birdwatchers to keep an eye out for this bizarre blackbird.

In the summer of 2011, park rangers took this picture of the blackbird - which is now entirely white with no evident pigmented feathers. According to Site manager John Clegg This bird has been steadily turning whiter over the years and last summer it was fully white. Each year, observers say, it has progressively shed its black feathers for white feathers.
