In order to avoid calamities, at first the kingfisher always selects a high place to build its nest.

But when the young birds are hatched, it will move to a place a little lower to build its nest. This is because the kingfisher is particularly fond of its offspring and is afraid they而ght fall down from a high place.

When the young birds grow beautiful feathers, the kingfisher will become even fonder of them and more protective, so it will move its nest further downward, with the result that the young birds are easily taken away by people.
