Although I've been aware of it, until all the snow
this week I've never wondered why so much niger seed
seems to be thrown onto the ground by the burds.

Is it really just discarded, or does niger seed,
despite its small size have a hard seed case that the
birds have to remove, and that is what I see scattered
on top of the snow?

The goldfinches that take the niger seed from my feeder are messy
eaters. For every seed they eat a couple of seeds drop to the ground
where other birds eat them.
