TROGON MELANOPTERUS, Swains.
Black-winged Trog-on.
(Young male.)
In the foregoing Plate I have illustrated an adult male and female of this Sue species, and in the description
I have mentioned the great difference in the colouring of the sexes, and the circumstance of the plumage of
the young male of the year being strictly similar to that of the female; the present Plate represents a young
male in the intermediate state, when, as will be perceived, it has partially acquired the rich purple of the head,
and the mature tail, with the exception of one feather, which still retains the characteristic markings of immaturity.
I would he're repeat that the adult male of this species has the three outer tail-feathers on each
side black at their base with tips of pure white, while the same feathers in young males of the year, and in
the females at p ag es , are strongly barred with black and white. These changes are always effected by the
acquisition of new feathers.
