Glossy vs White-faced Ibis

Pyle, 2008. Identification Guide to North American Birds, Part II.
(Copied with permission from the author.)

Known to many as The Banders' Bible, "Pyle I and II" are my go-to resource for tricky IDs.
I highly recommend these two books to anyone interested in bird identification!
