This censer is unique. Other bird-form censers are rarely as elaborately decorated as the present lot and tend to have the entire body in cloisonné enamel with the feathers and plumes detailed. Cf. the 18th-century censers, one in the Clague Collection, illustrated in the Catalogue, pl. 61; a pair of doves from the Pierre Uldry Collection, illustrated by H. Brinker and A. Lutz, Chinese Cloisonné: The Pierre Uldry Collection, pl. 324; and a pair of quails, illustrated ibid., pl. 328.
