Impressive feats of memory in nature

I was watching a documentary about Yellowstone recently and came across a scene on this bird called the Clark's nutcracker.
To summarize the story: They can plant 3000 sets of seeds cross 100 square miles and remember the location of 2100 even after they've been snowed on.

"With so many of its seeds sacrificed to fatten up woodland mammals for winter, a Clark's nutcracker is just what the whitebark pine has been waiting for to help it reproduce. With its perfectly shaped beak, the nutcracker prises the nuts from the cones and tucks them one by one into a special pouch under its tongue. Up to 150 at a time are stored, a fifth of its entire body weight. The nutcracker then flies as far as 15 miles away and drills the nuts into the ground in sets of ten, placing a stone on top of each stash to mark the site. Over the autumn, a single bird can bury 30,000 nuts across an area of 100 square miles. When the winter comes it will manage to remember the location of a staggering 70% of these seeds, even when hidden beneath the snow. But as the Clark’s nutcracker remembers its way into surviving the winter, it becomes the whitebark’s greatest ally. Although its feat of memory is extraordinary, for every thousand seeds it buries, it still forgets three hundred. From all those missed seeds, carried far and wide across Yellowstone, new whitebark pines will germinate next spring."

Do you guys have any other examples of impressive memory found in nature?

I read about that one indeed!

I also once read that ravens never forget faces, and whether the person is to be treated kindly or not. Chimps also appear to have a visual memory way better than ours. Elephants seem to be able to keep track of every single elephant in the group, which can be dozens. Nature sure has some impressive memories.
