See Zhongguo Meishu Quanji; Diaosu Bian (The Great Treasury of Chinese Fine Arts; Sculpture), Beijing, 1988, vol. 1, p. 84, no. 113 for a three-legged bronze bird dated to the mid Western Zhou period excavated in Baoji, Shaanxi province, with a similar head, beak, neck and scale-like feathers. Refer, also, to the flattened he dated late Western Zhou, with a bird-shaped lid, excavated in Qijiacun, Fufeng, Shaanxi province and now in the Shaanxi Provincial Museum, op. cit., no. 230. The bird-shaped lid compares very well to the present lot in the form of the beak and the stylized, folded wings.
