Both birds are still on the eastern end of the plum creek delta this evening. I was there close to an hour and they primarily stayed in the area where the American White Pelicans were staying. They flew together several times but stayed in the general eastern side of the delta. It is very muddy if you go along the shore. Not sure how you would get there through the trees. My eBird list said 0.67 miles from the nearest parking space. Thanks Joey for posting this very good rare bird for Chatfield. They were both still there at 5:30 PM today 8/24/19.
