Most of the time, the bird was hidden in the brush.

Bird was seen in a building materials dump.This part of the dump was not yet being used as a dump and was covered with willow trees and ragweed both on average about 5 ft high.

Most of the time, we couldnít see the bird.We did see it when it flew and sang except for twice when it sat in a bush or on a twig.

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. Stress features that separate it from similar species):

I will attach the photos that I took of this bird as a description to the email that I will use to send this report.I did not actually view it through binoculars because I was actively taking photos of it when it was at rest on a bush.I cannot take photos and view it through binoculars at the same time.

I personally heard it sing only once as it flew and it sounded to me like a Cassinís Sparrow.However, my hearing is very poor so I did not hear it as often as Terry Davis heard it.He can hear itchipping.

It sounded like a Cassinís Sparrow to me.
