    Default Leucistic(?) Crow 4-14-10

    More trips through the old photos. Two links were recently posted on Tweeters about an "Ino" owl recently photographed in Great Britain.

    According to the articles, an "Ino" bird is one that has the white feathers but not the pink eyes of an albino. The eyes of an Ino bird have normal pigment, which greatly increases its chances of survival over those of an albino. I always thought birds with white feathers and normal eyes were called "leucistic", but evidently there is a difference between leucistic birds and Inos. From one of the articles:

    Albinism is a congenital disorder characterised by the complete or partial absence of pigment in the feathers and Leucism is a condition in which there is partial loss of pigmentation in an animal resulting in white, pale, or patchy coloration of the feathers but not the eyes. Ino birds, are a genetic mutation of the two.

    On 4-14-2010 I photographed a crow at Marina Park in Edmonds that had white feathers and normal eyes. A leucistic bird or an ino bird? I'll post up the photos and the viewing audience can decide for themselves.

    More photos. I never did see that crow again.

    The crow had normal eyes. Its eyes are shut in this photo, which captured the blue eyelids.

    Pretty cool, Bill. I think there have been a number of sightings of leucistic ravens on Vancouver Island over the years.

    btw- I had my first similar encounter earlier this year, seeing a semi-leucistic robin in Yellowstone.
