Red Rocks Lakes NWR, Montana. I just shot this bird on the way to and from YNP, not even knowing what type of warbler it was until editing my photos. If I had only known, I would have spent far more time on it. There are 50 reported sightings of this bird in Montana, the vast majority in the Eastern prairie. There have only been a handful of Cape May Warblers reported in Western Montana where this one was shot.
