8. Other observers who independently identified the

None yet.
9. Light conditions (position of bird in relation to
shade and to direction and amount of light):
Sunny day, a few clouds. Sun was in the west, I observed the bird in
the easterly direction. The light was
very good.
10. Optical equipment (type, power, condition):
Lica
binoculars, 10x42.
However, I did not use them to observe the bird because I was taking
photos of it. I observed it through the
lens of the camera.
11. Distance to bird(s):
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 Cassin’s Sparrow at Cane’s 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.
13. Habitat:
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 couldn’t 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.
16. Voice:
I personally heard it sing only once as it flew and
it sounded to me like a Cassin’s 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 Cassin’s Sparrow to me.
18. Photographs or tape recordings obtained? (by whom? attached?):
Photos taken by Jeff Trahan using a Canon EOS 50D
SLR camera with a 400 mm Canon f/5.6 lens.
The bird was about 30 feet away when I took the photos. These photos are attached to the email that I
used to sent this report. Most photos were taken from about 30 feet
away. One of them was taken from about
80 yards away—this is the one showing only the back of the bird.
19. Previous experience with this species:
Seen several times in Arizona and
Texas and also Bossier Parish, LA in May 2008.
20. Identification aids: (list books, illustrations,
other birders, etc. used in identification):
a.

None
b.

is that of a Cassin’s Sparrow.
