ID help

Athens, Georgia - I was out on a hike at a nature preserve yesterday and spotted these birds fishing in the shallows of a creek. I didn’t have my binoculars and could only get so close without being a bother. The white bird is only about 2 Feet tall, it was hard to get a good look at its beak but it was darker colored (not orange or yellow). Legs were also not a bright color. I couldn’t get a good look at the feet as they were below the water the whole time I observed them. THE brown/white birds had a white underbelly and long downward curved beaks. I haven’t seen these birds in this spot before but they were there feeding for most of the day. Sorry the picture isn’t the best quality but I couldn’t get any closer. Any help with ID would be greatly appreciated. I have some ideas but I would love to hear what y’all think. Thanks :)
