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.
Recessive Pied budgerigar mutation in appearance to the wild-type Light Green. That is, the presence of a single wild-type allele is sufficient to permit the full production and normal distribution of the black melanin pigment. Among the budgerigar fancy such a bird is said to be a Light Green split recessive pied, usually written Light Green/recessive pied. In a bird which has two Recessive Pied alleles (the homozygote, "r / r" ), the lack of the wild-type allele means that normal black melanin pigment is suppressed in random areas over the body. The factors governing the distribution of the residual pigmentation are not known.
