For those who are interested, Dave Johnston has posted a couple of photos of the Vernon gambel's on vt ebird. You can quite clearly see the two most important field marks - the unmarked lores and the orange-tinted bill. I am not sure about the status of this race in vt but this is the first that I have heard of in my 10 years here.
