Owls feathers are different. They don't hook together like other
birds.

With a normal feather, if you ruffle it, it will divide up into clumps of
feather sections. And if you then pull it thru your fingers the bits will all
join back together. I don't think that is the case with owl feathers. A lot of
the noise is the feathers popping apart and reconnecting.
