That shown is the condition of the mounted specimen (Fig. 3). istics of the Mandarin Duck's "sail". One of these coverts on the left wing of specimen R-2 was very similar to the reduced "sail" of specimen L-1, but was even more strongly rufous on the inner vane. One other scapular on the opposite side of R-2 was of elongated shape but rufous coloration, and three of the longer scapulars on the other bird had the same rufous or rufous and black pattern on one vane.
