In the desert, some owls like to nest in the giant pillar cactus, they hollow out the giant pillar cactus directly in the inside of a home, the giant pillar cactus as a summer villa, this is obviously a very clever move, one is to use the giant pillar cactus to defend against foreign enemies, the other is because the giant pillar cactus contains a lot of water, if you live in it, you can avoid the hot weather in the desert.
And these giant pillar cacti also have a very good ecological effect on the desert, around the giant pillar cactus can form a small natural ecological circle, not only birds of prey such as owls, but also animals and insects living underground.
