Well, it's not exactly common, but this type of missing pigment is known to occur in a wide variety of bird species.  It's sometimes called "partial albino", but I think the preferred term is "leucistic".  Usually the lack of pigment just affects a small part of the bird, but sometimes the whole bird is distinctly paler than normal.
