We spent an hour down at Shell Point this morning and found a small flock of Savannah Sparrows that were being accompanied by a single Vesper Sparrow; a.k.a the "poor man's longspur." Vesper Sparrows have bold streaks on the underbody and have warmer brown tones to the upperparts unlike the vaguely similar but colder grayer looking 1st winter Chesnut-collared Longspur. Smith's Longspurs have warm upper and underpart tones but they also lack the bold streaking on the underbody and they lack a distinctive white eye-ring, which is the first obvious feature I note on a Vesper Sparrow. This individual obliged a close approach so I could get some reasonable digiscope pictures.
