Question: What is special about this species' method for storing food?

The Clark's Nutcracker is known to cache its nuts that it finds. 90 percent of the time( correct me if I'm wrong) they find the nuts but the 10 percent will germinate and grow into a plant. So the Clark's Nutcracker is largely responsible for reseeding forests.

Correct. I was actually also looking for the birds exceptional spacial memory which allows it to locate the majority of the caches, but your answer works too.

that's not on the national list, is it?

Yes it is. It's a corvid.

indeed it is... sorry, I don't do the passeriformes in detail, only an ID knowledge
