I didn’t see any American Robins feeding on crabapples yesterday but I did find a leucistic Canada Goose at my local pond.

The leucistic Canada Goose was bathing when I first noticed it along the shoreline. My photos were taken from the opposite side of the pond for documentary purposes.

I thought the white markings on the left side of the head of the goose were interesting. I really wish this odd looking goose had been closer to me.

Leucism can affect part of a bird or the whole bird. In this case the rest of the Canada Goose appears normal. Only the goose’s head shows the plumage variation so I would call this Canada Goose partially leucistic although some people might call it piebald or partially albino.

What is Leucism?

From Wikipedia:

‘Leucism’ is often used to describe the phenotype that results from defects in pigment cell differentiation and/or migration from the neural crest to skin, hair, or feathers during development. This results in either the entire surface (if all pigment cells fail to develop) or patches of body surface (if only a subset are defective) having a lack of cells that can make pigment.

David Sibley, the author of “The Sibley Guide To Birds”, shares his thoughts on abnormal coloration in birds here. I have that post bookmarked and refer to it whenever I find a bird with abnormal coloration or leucism.

The right side of the Canada Goose’s head looked normal except for a spot of white above the cheek patch that extends from the left side of its head.

Over the years I have photographed other birds with abnormal white plumage including a Black-billed Magpie, Red-tailed Hawk, Bald Eagle, an American Robin with one white tail feather, and white Eared Grebes on the Great Salt Lake.

Not only am I always looking for birds I am also looking for the odd duck, or in this case, the odd goose.

Life is good.
