Leucistic form information _ Fredericksburg.com - WHITE-HEADED ROBIN SPOTTED






Fredericksburg.com - WHITE-HEADED ROBIN SPOTTED



~ text, from NBB'er JB

article with photo of a white-headed robin that looks similar to yours, but
was seen in Virginia in 2009. The article has a good explanation of the
phenomenon. See
