Hi all, My tentative guess is the fruit is European buckthorn. 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.
