More on the Copper's Hawk

Beyond being surprised to see this Copper's Hawk on our back yard fence yesterday, we were also intrigued to notice that it was leucistic.  Leucism in birds is a condition in which there is a loss of pigmentation which results in patches or areas of pale or colorless feathers. Since learning of this condition a couple of years ago, we are surprised how often we see birds with this strange white coloring. In the case of this hawk, the leucism shows up in a white patch on the top of the head.
