Saw 2 spinning things like a tornado but the size of a bird, then a third, pass the moon.

I was looking out the window at the moon and taking pictures of it. I have a clear view. Then I saw two spinning objects, crossing from the right, either behind or in front of the moon. They looked like bird sized tornadoes. After it passed the moon, I watched them continue to go, and then noticed a third one coming from behind, looking just like the others. I watched all three trail off into the dark until I could no longer spot them.
