It is the story about a mother bird who knows her egg will be in her nest where she left it, so she leaves him alone to go and get something for him to eat. The baby bird hatches. He doesn’t understand where his mother is so he goes to look for her. In his search, he asks a kitten, a hen, a dog, and a cow if they are his mother. They each say, “No.”
Then he sees an old car, which can’t be his mother for sure. In desperation, the hatchling calls out to a boat and a plane, and at last, convinced he has found his mother, he climbs onto the teeth of an enormous power shovel. But he is betrayed by the behemoth, as it shudders and grinds into motion. He can’t escape. “I want my mother!” he shouts.
But at this climactic moment, his fate is suddenly reversed. The shovel drops him back in his nest, just as his mother is returning home, and the two are reunited, much to their delight. He then tells her about the adventure he had looking for her.
