昨天松鼠跑进公寓大院，稀客啊，我给它一颗花生米，它捡了咯嘣咯嘣吃了。又有人给
几颗杏仁，它捡起就埋旁边的地里。
查了下：
“First let’s lay a foundation – Not all squirrels bury nuts. Gray
squirrels do bury things like acorns and walnuts, but red squirrels do not.
Red squirrels horde their nuts in piles. As described in this article, these
two different behaviors can have a big effect on a forest. Gray squirrels
do not recover all of the nuts that they bury, and these nuts go on to
become trees. Red squirrels horde their nuts above ground, and those nuts
never germinate. From the forest’s perspective, gray squirrels are better.
So how do gray squirrels find all the buried nuts? As described in the
article, they don’t find a lot of them. To be more specific, this article
points out that gray squirrels only find 26% of their buried nuts. In other
words, the majority of nuts that gray squirrels bury stay in the ground, and
have the potential to sprout.
How do gray squirrels find the nuts that they bury? Obviously, in most cases
, they do not find them. But they do find some. It is thought that they
remember where they bury some of the nuts through landmarks, in sort of the
same way you remember (or don’t remember) where you left your car keys when
you got home. ”
