Recently I received a call from my daughter. She was excited because her new feeder cam recorded the appearance of a partially white female cardinal. Ornithologists refer to this condition as partial leucism.
White cardinals can be partially either partially or totally white (true albino). Cardinals that display “white” are very rare. The odds of seeing a cardinal that displays any white feathers are 1:30,000. Total albinos are much rarer the those birds that show patches of white. According to Avian Report out of every 100 “white” cardinals seen, 82 are partially white and only three totally white.
Your chances of spotting a yellow northern cardinal are one in a million. Several years ago I was extremely fortunate see one of these birds in a Macon backyard.
