This video from Canada says about itself:

Have you ever noticed a bird whose plumage coloration looks odd or even abnormal? Then you may have spotted a bird that is affected with leucism – like this male Pine Grosbeak that visited the Ontario FeederWatch Cam this morning. Leucistic birds have a genetic mutation that prevents melanin and other pigments from being deposited normally on feathers, resulting in pale or muted colors on the entire bird.
Thanks to Perky-Pet for helping to make the Ontario FeederWatch Cam possible!
The FeederWatch cam is located in a residential neighborhood in Manitouwadge, Ontario.
