For the buntings/longspur and horned lark you need to look for small birds in mixed flocks on fields; those I remember from way back were flocks where we hit them randomly driving through the landscape and then stopping to see what they were. I remember house finch as much more common then purple.
I lived in WI for 2½ years, but back mid 90ties.
