Those are birds and yes they can fly in groups that big like that.

If anyone other than a complete spaz was holding the camera it would be incredibly easy to tell those are birds. 

If aliens do exist I sure they are friendly if not they would have already kill us.

oh man!!! theres one close up @ 0:42

unless someone catch a nude female alien
those so called 'UFO" video dones't interests me anymore

The things that makes this seem fake to me was that the person claims to taken it in New York City. How can you be in the most densely populated city in the United States and be the only person to see squadrons of UFOs in the sky? Also why does he seem to be incredibly calm about the whole thing?  Oops nevermind they're birds.

There some dopy birds most of the birds i see in the UK fly in nice V shapes that is just a mess, how are they gonna get there speed boosts.

Firstly the person holding the cam has Parkinsons so it's hard to really make out anything but that would also be a mighty strange formation for a fleet of UFO's to be flying in.

those didnt really look like birds to me but more like colored dots

Doesn't look like birds to me, looks like dots trying to form a picture, if they are birds they are on LSD or something.
