Saw these fly objects while presidential ospreys and marine 1 were leaving JFK

I've seen ospreys and marine 1 many times in and out of JFK, What I saw here is nothing like I've seen. As I was walking to the back yard with my infant son, the first couple of seconds, I thought I was looking at birds but none of the wings were flapping. These objects were moving consistently in one direction. Im familiar with drones and know JFK is a no fly zone but I couldn't come up with what these could be. I didnt assume weather balloons and lanterns simply because of the airplanes.
