Song Dynasty or earlier (960-1279)
The bird is carved with a long sweeping tail curved inwards, with the wings and eyes accented with deep grooves. The back of the neck is drilled to allow for suspension. The jade colour is an overall greyish white with a small patch of russet skin on the head of the bird.
A white jade example of a bird with russet inclusions dated to the Song dynasty can be found in Jades from China, Bath, 1994, p. 320, Catalogue No. 236
