30 to 50 feet

12. Duration of observation:

About 20 minutes

13. Habitat:

A field with tall leafy weeds.  My companions said giant ragweed but I'm botanically illiterate; see the photos.

14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation):

The bird would perch on top of the weeds, often singing.  It would fly up about 20', curve horizontally about 20', and drop down, usually not returning to its original perch.  It sang in the air as well as when perched.

15. Description (include only what was actually seen, not what "should" have been seen; include if possible: total length/relative size compared to other familiar species, body bulk, shape, proportions, bill, eye, leg, and plumage characteristics.

A relatively large, long-tailed sparrow.  See the photos.

The song was in four parts.  The first, third, and fourth parts were brief; the second part was a longer trill.  The voice was loud and distinctive, matching the recording we listened to earlier (respecting Terry Davis' wishes, we didn't use a recording at the site).
