Shorebirds always challenge my identification skills. I decided it was time to review various material I’ve seen. I thought maybe the list could be beneficial to others even if it wasn’t all encompassing.
I started by adding this bookmark from Audubon to my birding backpack so I have it for quick reference:

I recently received an email from Audubon with a link to this article. It has some good overview information: Shorebirds 101: What to Look for When You Hit the Water
Bob Mercer has created the Field Guide to the Shorebirds of North Beach, Seabrook Island, SC. It is designed to be printed as a booklet. Printing is to be done double sided and flipped on short side. When done that way, the birds end up next to the description.
Seabrook Island Birders has also presented several shorebird programs that have been recorded which are available for watching at any time:
Janet Thibault: Seabrook’s Amazing Shorebirds!
Bob Mercer: Shorebird Identification on Seabrook Island, South Carolina
I hope these materials are helpful to you as they have been to me.
