There's a wind shear up there across an air density jump. Like water waves, that's unstable and various length waves start growing. The fastest-growing wavelength takes over the sky.
Riding with the waves, nearly condensed water vapor condenses and uncondenses as it goes up and down giving the herring bone pattern.
Anyway the pattern size is from the size of the most unstable wave.
I liked The Birds enough that I used to vacation in the towns of Bodega and Bodega Bay. I visited the site where the school scene was shot, not that that is anything to crow about.
It was just a short drive up the road and bam, there you were in a great, little-known (at least at that time) state park. We had some good times up there.

Cirrus as I can be, I'll tell you what.

All those crows just wanted to get a piece of Tippi Hedrin.
That's a terrible thing to say but I can't help myself. :^(
@rhhardin: What a splendid explanation. Thanks for that!

Heh. We did the same when based up on Bartlett St. in Sunnyvale.
