In my last sentence I of course should have included Henslow's Sparrow.

"That said, it's possible Nelson's and Le Conte's could be quite a bit more
widespread, and we're limiting ourselves by locking in on the first few
sites where they're seen. I for one am particularly curious about what
habitats Le Conte's sparrow's prefer during migration. Perhaps a bit drier
than that used by Nelson's."

In Milwaukee along the Lakefront we have found that Nelson's are easier to find
than LeConte's in fall and there may be some habitat preferences. Both are
attracted and found at sites with lots of water smartweed and wild sunflowers
with lower ground cover where they feed at the lowest flowers. In the early
days of the Milwaukeee Coast Guard Impoundment there was a construction road
that went through the new fill that had only smartweed growing on either side
of the road; one could find 17 species of sparrows in early October. I feel
that Nelson's may flock somewhat as well as I have had groups of up to 9
Nelson's together in huge expanses of smartweed. One finds LeConte's as
solitary birds generally. And if one flushes an Ammodramus from a drier,
shorter, grassy-weedy edge it will probably be a Grasshopper or a LeConte's
Sparrow.
