Cassin's Finch - a brief stop allowed time for a final mosey into an area of open pine forest, and by sheer luck, a small group of these hard-to-find finches dropped in almost at my feet, fed for several minutes, and were on their way into the wilderness
Dark-eyed Junco - as mentioned previously, local birds are of the Pink-sided subspecies, which occupy a limited breeding range pretty much restricted to eastern Montana and north-west Wyoming
male Lazuli Bunting - unmissable
Vesper Sparrow - somewhat more missable
a mixed flock of Barrow's Goldeneyes and Lesser Scaup on Yellowstone Lake. The former were new for me, and I'd imagined I'd struggle to find them on remote mountain lakes - as it happened, they were far and away the commonest duck species, with many hundreds present
Barrow's Goldeneyes
Osprey getting a kicking from a local Raven
Gray Jays (of the pale-headed, Rocky mountains subspecies); another species I'd expected problems locating, and so it was, until basically hand-feeding a small party at a picnic site
