There seem to be lots of variations on this song:

Lyr. Add: The Owl in the Elm

The owl cries from the elm tree
Soon as the darkness falls;

While from the hills in answer
A cuckoo softly calls;

Cuckoo, cuckoo, cuckoo, cockoo.

"Dutch, a round"

With music, p. 17, "Chansons de Notre Chalet," 5th ed., 1971, put out for Girl Guides and Girl Scouts (Co-operative Recreation Service, Inc., Delaware, Ohio, or Our Chalet, Eggertli, Switzerland). I can't find any recent reissues of this song booklet.
