seed-eating bird

The bird Clark's nutcracker, for example, hides up to 100,000 seeds per year, up to 30 kilometers away from the seed source, and has a very close symbiotic relationship with several pine species, most notably the whitebark pine.

比如说，一种叫北美星鸦的鸟每年会储藏多达100，000粒种子，储藏在距离种子来源地30公里以外的地方，这种鸟与一些种类的松树存在着密切的共生关系，这些松树中尤其以白皮松居多。
