Black Skimmer Skimming Along

We went to the Brigantine Division of the Edwin B. Forsythe National Wildlife Refuge in Oceanville, NJ. We were hoping to see the usual Herons & Egrets, Ospreys, Hopefully Bald Eagles, Harriers,Oyster Catchers, etc. There are also Black Skimmers but usually they seem to be quite far out when they are skimming along feeding. I was photographing some Great Egrets when 2 Black Skimmers flew by feeding close to shore. They went back and forth a couple of times before moving on. Here are 2 from the series.
