How can one distinguish one Canada Goose in a flock of a few hundred? It is easy if that goose is leucistic.
A leucistic animal is one where some region of its pelage lacks pigment. It is not an albino, which describes a complete lack of pigment throughout the body. For the leucistic animal, the pigment loss is just local.
A leucistic female Canada Goose has been seen around the Lake for over a half-dozen years, but I last saw it four years ago. As the Canada Goose can live for a couple of dozen years, we may continue to see her for a while longer.
A Canada Goose — nicknamed Lucy for being leucistic — was spotted along the shore among other geese. Her normally whiteish chinstrap is slightly beige, but her leucistic cap lacks all pigment.
