Trog on pavoninus. Spix, Av. Sp. Nov. vol. 1. pi. xxxv. p. 47- 
The Irogon pavoninus was first described by Dr. Spix in bis work on the birds of Brazil. His account of 
it, however, is so meagre as to afford us but little insight into its history: and twelve years have now elapsed 
since the publication of his work without any additional information having been made known. Through the 
kindness oi M. Jean Natterer of Vienna, I am enabled to illustrate both sexes of this species, from very fine 
specimens which he has confided to my care for that purpose. During his sixteen years’ sojourn in the 
Brazils, M. Natterer had frequent opportunities of observing this bird in a state of nature ; and he informs me 
that it inhabits the high woods bordering the upper parts of the river Amazon and the Rio Negro, where it 
is only seen among the highest branches of the trees. 
Upon examining the contents of the stomach M. Natterer has almost invariably found it to consist of the 
fruit of a certain species of palm; he therefore concludes that this, together with various berries and stoned 
fruits, forms its subsistence. It arrives in the localities above mentioned when its favourite fruit is ripe; and 
when the trees no longer yield an adequate supply it retires again to other districts. In the nature of its food 
this bird differs from most of the other species, which are well known to subsist principally on insects ; and 
its difference in this respect is accompanied by an equal diversity of form, the wings being more lengthy, 
the tail less abruptly truncated, the bill destitute of serratures, and the claws strong, curved, and admirably 
adapted for clinging. 
In my description of the magnificent species from Guatimala which I have designated resplendens, I have 
pointed out the characters by which that bird may at all times be distinguished from the one now represented ; 
it will therefore be unnecessary to repeat them here. 
Although the females of this bird and of Trogon resplendens offer a considerable difference in their plumage 
from each other, yet they assimilate more nearly than do the females of most other species ; for they both 
possess the rich glossy green plumage, and the upper tail-coverts are alike, but in the present bird they are not 
so elongated as in Trog. resplendens. The young males during the first year resemble the female.
