The first photo, from a year ago, shows how most bird guidebooks portray a female Yellow-bellied Sapsucker, white throat and red crown. The second photo, taken three days ago shows the unusual "Black Crown" variant. I was baffled when I took her photo, so I sent it off to a couple bird experts. One, arguably the best birder in the state, is 85 years old and has been birding since he was five, said he had never seen one. He did say the current Sibley depicts it, but my older version does not. I also searched on-line and found a few other references to this plumage, but only a few. Most unusual!
