LOCALITY OF OBSERVATION
Teton River between Hog Hollow Road put in and the Old Dam. We encountered the birds about halfway down the float along the bank of the Teton River.
HABITAT WHERE THE BIRD WAS OBSERVED
Grassy bank and silted eddy off main channel of river.
SIGHTING DURATION, CONDITIONS, and EQUIPMENT USED
Siting was about 5 minutes in broad daylight from our raft. We pulled over to view them and they seemed to be unphased by our presence and continued to feed in the silted in bottom of the eddy. The weather was 80 degrees and sunny. Very little wind at that time. We came within 8 feet of the birds on the bank/river.
DID YOU TAKE NOTES?
No, not at all
DID YOU CONSULT A FIELD GUIDE OR OTHER REFERENCE WORK?
Yes, later the same day
WHICH GUIDE(S) OR REFERENCE(S): DID YOU CONSULT?
Online resources and Mary Holland, Naturalist in Vermont who is acclaimed author of many nature books (and my Aunt!)
DESCRIPTION OF THE BIRD(s)
Long curved bill similar to white ibis. Brown head and darker brown body with teal/darker green iridescent wing feathers.
BEHAVIOR OF THE BIRD(s)
Calmly feeding on river bottom and standing in grass.
HOW AND WHEN DID YOU POSITIVELY IDENTIFY THE BIRD, AND WHAT CLINCHED THE IDENTIFICATION FOR YOU?
I sent a photo to my Aunt the evening of the siting and she confirmed the bird as she has seen them in the wild.
HOW DID YOU ELIMINATE SIMILAR SPECIES? WHAT WERE THEY?
NA
WHAT IS YOUR EXPERIENCE WITH THIS (AND SIMILAR) SPECIES?
None to date
DESCRIBE YOUR GENERAL BIRDING EXPERIENCE
I do a fair amount of amateur birding as I had access to Ding Darling Wildlife Sanctuary as a child in Sanibel Florida.

FIRST ROUND VOTING:

Cliff Weisse
Reject, specific identification not established

White-faced ibis can not be ruled out by these photos.

Shirley Sturts
Reject, specific identification not established

The similar White-faced Ibis was not eliminated and the photos were not helpful.

Dave Trochlell
Reject, specific identification not established

These appear to be Plegadis ibis in non-breeding plumage, and as such a White-faced Ibis may be indistinguishable from a Glossy Ibis.

Carl Lundblad
Reject, specific identification not established

Juvenile Plegadis aren't considered identifiable. It's not clear why these were identified as Glossies, there is no description or other documentation that supports that ID, and no attempt made to eliminate the expected species.

Doug Ward
Reject, specific identification not established

No definitive marks noted by observer and without comparison to expected White-faced Ibis (Plegadis chihi); photos indicate the later.

Darren Clark
Reject, specific identification not established

The observer separated the bird accurately from White Ibis, but not from White-faced Ibis. This is nearly impossible in this plumage.

Jay Carlisle
Reject, specific identification not established

juvenile ibis - extremely difficult to differentiate species in this plumage but I don't see anything diagnostic of Glossy so I presume White-faced
