“I also keep a jar full of raven feathers in the storeroom, kindly donated by the ravens once a year during their molt, and which I occasionally like to distribute to deserving/well-behaved/lucky visitors. If I’m doing a Tower tour, for example, and I discover that a couple just got married or engaged, I like to give them a pair of feathers—a primary and a secondary, since without one the other is no good. I’m an old romantic at heart.”
