with along with flocks of other birds—Flycatchers, Tanagers, Creepers, Woodpeckers, 
&c., that hunt together, traversing the forests in troops of hundreds belonging to more 
than a score of different species. . . . . The Flycatchers and Trogons sit on branches 
and fly after the larger insects, the Flycatchers taking them on the wing, the Trogons - 
from the leaves upon which they have settled. In the breeding-season the Trogons are 
continually calling out to each other, and are easily discovered. The Spainards call 
them ‘Viudas.’” 
Mr. Richmond says!§ that Trogons are almost invariably found in pairs (probably 
during the breeding-season), rarely in small flocks. He adds that the iris of this 
species is very dark brown, the feet plumbeous, the orbital ring blue, and the bill 
chromium-yellow. 
In Costa Rica this species appears to be equally common, and also in the State of 
Panama, both in Chiriqui and along the Line of Railway. 
In South America it is represented in nearly every collection of any extent formed 
in lowlying forests of the hotter parts of the continent.

Little has transpired concerning this fine Trogon beyond the account of it given by 
Salvin in the second edition of Gould’s ‘Monograph of the Trogonide,’ which we 
transcribe below. The range is now found to be a little more extended, as Arcé sent 
us an adult male from Veraguas, and we have adults of both male and female from the
