Last spring Leonard and I discovered a partially leucistic Canada goose at Ash Creek Wildlife Area (Lassen County CA). Last weekend, much to our surprise, we found another partially leucistic bird, this time a sandhill crane (Antigone canadensis). This rare specimen was also in the wildlife area, not far from where we saw the leucistic goose.
Animals and birds that are leucistic have a partial to total loss of pigmentation, a genetic condition that is not the same as albinism. This partially leucistic sandhill crane is lacking pigment in the shape of an incomplete collar at the base of its neck.
My post on the partially leucistic Canada goose (Leucistic Canada Goose 04-07-21) covered this condition thus I will not repeat the information. Instead I will simply share the pictures.
