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 in- 
foims me that he once observed this species in company with the Trogon variegatus, 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 re¬ 
mains 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.
