28-B-2018 Glossy Ibis
FIRST ROUND VOTING:
White-faced ibis can not be ruled out by these photos.
The similar White-faced Ibis was not eliminated and the photos were not helpful.
These appear to be Plegadis ibis in non-breeding plumage, and as such a White-faced Ibis may be indistinguishable from a Glossy Ibis.
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.
No definitive marks noted by observer and without comparison to expected White-faced Ibis (Plegadis chihi); photos indicate the later.
The observer separated the bird accurately from White Ibis, but not from White-faced Ibis. This is nearly impossible in this plumage.
juvenile ibis - extremely difficult to differentiate species in this plumage but I don't see anything diagnostic of Glossy so I presume White-faced
