Last night at dusk (8:30ish), two Black Skimmers were working the Shorebird Pool near the guardhouse. As far as we know, that was the first sighting of the year.
Note: Sorry — In the above post I was thinking of DeKorte Park, where the skimmers can really put on some amazing aerial shows for all to see. This spring skimmers have also been seen in Harrier Meadow, by the legendary Meadowlands Marsh Hawks, as well at the Clay Avenue wetlands by Michael Mastropasqua. Thanks to the eagle-eyed readers who pointed out the error of my (hasty) ways.
