Rob, et al, Yes, European Buckthorn. I agree that is what all the pics people have been sending seem to show the bird is eating. Yes, it is widely planted, and yes, it escapes, gets spread, definitely deserves the moniker of "invasive exotic". Thanks to all who have sent me photos. Interesting situation. Birds do what they have to do. Insects are probably what these neotropical migrants want as a first choice, but in a pinch the Ovenbird in Bill's yard and this Prothonotary clearly prove they can handle millet and fruit, respectively, and probably a lot of other things if they get desperate enough.

Dave Leatherman, would you confirm or refute? If it is, do you see a lot of this in Colorado? It’s unfortunately fairly common where I live. Definitely an invasive exotic, but birds like the berries and contribute to its spread as a result.

This is perhaps a cherry on top of the November warbler parade in Colorado, which by my count now totals at least 13 species (Tennesee, Orange-crowned, Northern Parula, Yellow-rumped, Black-throated Green, Pine, Palm, Bay-breasted, Blackpoll, Prothonotary, Ovenbird, Common Yellowthroat, and Wilson's). Intrigued by Steve and Cheryl's reports of "hawthorn", chokecherry (its fruits should be long gone or dried up by this date but it could have lingering aphids), or some other woody berry plant being involved in the diet of this Prothonotary, I check the BNA account. There is one winter diet study in Panama that listed fruit as making up 10% of the diet. I would really appreciate confirmation this bird is, indeed, eating fruit and what kind of fruit it is.
