Leucistic American Robin - Birds and Berries - Part 6

This bird is definitely lacking some colouring on its head which makes it fit into the more general description of how leucism is defined. There can be more striking examples of this phenomenon in which the bird is almost pure white but still has normal coloured eyes instead of the pink eyes of albinos. In mammals this condition (mutation) is often referred to as piebald. This American Robin was part of the larger flock of robins pictured in the previous post. November 11, East Jordan NS.
