Honeybees use the sun as a compass

Bumblebees actually use the sun as a compass to keep track of where they come from and where they go. They do this in a very advanced way, using a polarizing light to keep track of their location, even when the sun is covered by clouds. This is very useful, as it allows bees to track where they find flowers and other things of interest, and it allows them to find their way back to their hive with ease.
