under parts are strongly washed with ochraceous. ‘This bird is 
probably older than no. 8553, as several of the chestnut feathers, 
characteristic of the adult, are appearing on the crown. No. 8555 
has nearly attained the adult dress, but still retains the postocular 
stripe (which becomes quite obsolete in the adult) and has the 
under parts still washed with ochraceous. No. 8556 is similar to 
it. 
The olive cap, the pale postocular stripe and the ochraceous 
tinge of the under parts are all merely marks of immaturity, and 
gradually disappear as the bird attains the plumage of the fully 
adult.
