From "rediscoverer" to "he who claims"

An excerpt from this BirdChick post:

I have to admit that I got a kick out of the announcement that read "The Oak Savanna Birding Festival will feature a presentation by BOBBY HARRISON from Huntsville, Alabama. He is one who claims to have seen the Ivory-billed Woodpecker." It's gone from "rediscoverer" of the ivory-bill to "he who claims". No matter what side of the fence you are on, Bobby is a great story teller and more than worth the price of admission.
