The rich golden green of its. plumage, together with the brilliant scarlet of the breast, the strong and decided
markings of the tail, and the perfect pectoral band of white, are the principal features by which this elegant
species may be distinguished from its congeners; for although the Trogon elegans possesses almost the same
style of markings, the transverse bars of black that vary its much more elongated tail are considerably finer
and more numerous..
The Trogon collaris is found in Brazil and Cayenne, from any localities to the north of which countries I
have never seen specimens. Although different members of these birds rarely associate, yet M. Natterer informs
me that he once observed this species in company with the Trogon mriegatus, on the banks of the
Rio Negro; and he considers that in all probability they were effecting a partial migration, from one part
of the country to another: the stomachs of several of this species which he examined contained the remains
of fruits and caterpillars.
The plumage of the sexes differs considerably; those parts which in the male are rich golden green, being
of a deep brown in the female: the tail of the latter is also extremely different, being entirely destitute of the
strong bars of black and white which characterize that of the male.
