Something like that. I noticed the objects flicker the instant camera moved.
I was driving across the Lake Houston Parkway bridge late one day when suddenly a group of bright objects appeared in from of me in the sky. They turned out to be Pelicans. Their white undersides glowed like lights in the setting sun, but you could hardly see their dark backside when they turned.
I have seen glowing migrating geese. The city lights glow off their bellies. Looks cool.
