taken for clouds. Stas assumed that it was their pretty little bills which rang so, while in daytime they were scattered on single clumps.
But other birds flying in little flocks, which gave real concerts, filled both children with the greatest surprise and ecstasy. Every little flock consisted of five or six females and one male, with glittering metallic feathers. They sat on a single acacia in this particular manner: the male was perched on the top of the tree and the others lower, and after the first notes, which seemed like the tuning of their little throats, the male began a song and the others listened in silence. Only when he had finished did they repeat together in a chorus the last refrain of his song. After a brief pause, he resumed and finished, and they again repeated; after this the whole flock flew in a light wavy flight to the nearest acacia and the concert, composed of the soloist and chorus, again resounded in the southern stillness. The children could not listen enough to this. Nell, catching the leading tune of the concert, joined with the chorus and warbled in her thin little voice the notes resembling the quickly repeated sound of "tui, tui, tui, twiling-ting! ting!"
Once the children, following the winged musicians from tree to tree, went away over half a mile from the camp, leaving in it the three negroes, the King, and Saba. Stas was about to start on a hunting trip and did not want to take Saba with him, for fear that his barking might scare away the game. When the little flock finally flew to the last acacia on the other side of a wide ravine, the boy stopped Nell and said:
"Now I will escort you to the King and after that I shall see whether there are any antelopes or zebras in the high jungle, for Kali says that the smoked meats will not last longer than two days."
