Baby King fisher

Are You dead ?
This bird fell from the nest located on the tree near the dog house last night. The ugly dog barked furiously and my maid brought the bird and put inside the bird cage. She said she also saw some broken blue egg shells nearby. Well, quite a news to me the eggs of the king fisher are blue.
I thought King fisher made nest near the stream or river bank on the ground. Why this one situated on the tree then? The poor baby bird is quite developed and perhaps still has not learned how to fly. 
May be the mother kick him out of the nest in order to learn to fly!
