Drones in the skies above New Jersey. What is going on?

[epicurean]

Its got to be the US government. Not sure if they thought they would go unnoticed or what. Seems obvious they are throwing out flimsy excuses/deflecting/etc.

No idea on the birds. They migrate. Can't tell from the video what direction (south?) they are going, but I see huge groups of birds like that all the time in the midwest.
