I saw these birds while walking through a salt water marsh in Hampton, Virginia. It was around noon on May 25, 2020.
As you can see there are 5 birds, but one is hidden. Two have yellow bills and black feet and the others appear to have black bills (at least the two you can see) and yellow feet. So it thought they could have been Great Egrets flying with Snowy Egrets but they all look to be the same size. I am very new to birding (about 3 weeks in) so I'm sorry if this a dumb question, but I would love to know what I saw. Thank you.
