Why is the kingfisher’s home on the stone wall?

The reason why the kingfisher’s home is on the stone wall

You know that kingfishers eat fish, and the feces pulled by fish-eating birds are white. If kingfishers build nests on a tree, there must be white flowers under the tree. Natural enemies can easily put them in one pot accordingly. Baihuahua’s feces are in the dirt cave, so it doesn’t matter. You would say that egrets also eat fish, why do they build nests in trees? Actually, I guess that the egrets also wanted to make their nests in earthen caves, but their size is too big to find such a big cave. .

The kingfisher’s nest is always located on the cliff facing the water. Predators who don’t like water cannot catch the little kingfisher in this position, and it is difficult to find this position on the shore. If I were a kingfisher, I would also put the nest Do it there because that is the best choice. Oh, I almost forgot, the kingfisher’s feet are very weak, almost incapable of grasping, and can’t rely on the claws to grab the nest material to build the nest, and can only use the cave that does not need the nest material.
