I've heard a lot of comments that these were birds that were tricked by the lights, but I think they're actually bats feeding on the insects that were attracted to the lights. I've never seen birds congregate like this, especially at night and around lights. I have however seen bats collect around stadium flood lights to feed on the insects that gather there. Also note that they are constantly flapping their wings - there are no gliders here.
