| Occurrence Remarks |
The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: Le Conte's Sparrow - eliminated by lack of orange, + by lack of streaks on side of breast Henslow's - eliminated by nape streaks, but it's hard to be sure. Perhaps the difference in color between a Henslow's face + Grasshopper's face would be hard to tell in a backlit bird. Looked pale, though. | The original documentation form event occurred in the afternoon for five minutes or more. |

| Event Remarks |
Distance: 15' ? educated guess. I was close. Optical equipment: 8.5x binoculars Light: Bad light - bird south of me, sun south west. Bird partly backlighted [sic], and dust on binoc. lenses shows up top. I felt I saw it well after a while. |
