It's entitled birds, but then the OP goes on to claim no way.

Sounds like you're already speculating, how have you determined the altitude of 20m?
And the speed?
I hear the argument that an object can't be a bird because it moves too fast all the time but never how one has come to that conclusion.
Without knowing size and distance from the viewer, we can't speculate on speed.
