   Hi Kate, Not to worry! This Common Grackle is not sick. Sometimes, birds may have an abnormality in the deposition of pigment in their feathers, which is most often genetic. When there are patches of white, this is called Leucism, or Pie-baldism. You can learn more about unusual color variants here: https://feederwatch.org/learn/unusual-birds/#color-variants
