Closest distance about 10 yards.† Farthest about 75 to 100 yards.
12. Duration of observation:
Terry Davis called me at 3:50 PM to tell me that he had found a Cassinís Sparrow at Caneís Landing in Bossier Parish.† I arrived at the location with my camera and occasionally saw the bird from about 4:30 PM until about 5:30 PM.† Total time actually seeing the bird was less than one minute.† However, it occasionally sang at the time it flew.† I stood in one location looking for the bird for a little more than one hour. †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.
14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation):
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.
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. 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 it† chipping.
17. Similar species (include how they were eliminated by your observation):
It sounded like a Cassinís Sparrow to me.
