Cydalise et le Chèvre-pied Cydalise et le Chèvre-pied Cydalise et le chèvre-pied ("Cydalise and the goat-foot" or "Cydalise and the satyr") is a two-act ballet originally choreographed by Léo Staats to a score by Gabriel Pierné. The libretto was written by Gaston Arman de Caillavet and Robert de Flers, based on Remy de Gourmont's "Lettre d'un satyre". Though it was composed between 1914 and 14 February 1915, its Paris Opera premiere was delayed due to the conditions of World War I until 15 January 1923. The use of the French term "chèvre-pied" (goat foot) to refer to the satyr is distinct to this composition.
Pied-winged swallow Pied-winged swallow The pied-winged swallow ("Hirundo leucosoma") is a species of bird in the family Hirundinidae. It has distinctive steel-blue upperparts with white wing patches. It is native to parts of West Africa. The pied-winged swallow was described by the English ornithologist William Swainson in 1837 who introduced its current binomial name "Hirundo leucosoma". The specific epithet combines the Ancient Greek words "leukos", "white" and "sōma, sōmatos", "body". The species is monotypic. Evolutionarily, the pied-winged swallow occupies a basal position within the clade of "Hirundo" swallows and is most closely related to the pearl-breasted swallow ("Hirundo dimidiata").
