Résumé :	The primary moult of small Accipitridae normally follows a single descendant sequence, while serial descendant primary moult (Staffelmauser) is typical in large raptors. Elaninae are considered to moult in a single descendant sequence. During a study of Black-shouldered Kites in the Western Cape, South Africa, six sub-adult birds (9%) and two adults (5%) replaced the primaries in a serial descendant pattern. Only a minority of juveniles underwent a complete post-juvenile moult; most replaced only contour feathers during the first moult.
