Three different first calendar year immatures, all at different stages of moult into first winter plumage (see comments). All three have developed the typical two tone pink based and black tipped bill of first winter plumage but feather moult is different in each individual: 1. The first individual has begun to moult its mantle and scapular feathers but the wing coverts are still juvenile. 2. The second individual shows even more advanced scapular moult and the greater coverts are also more developed. 3. The third individual has nearly moulted all its scapulars, mantle and greater coverts. Elevation: 6 m. Date added to IBC: January 20, 2018.
