With along with flocks of other birds— Flycatchers, Tanagers, Creepers, Woodpeckeis, 

 &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 Eica this species appears to be equally common, and also in the State of 

 Panama, both in Chiriqui and along the Line of Eailway. 



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 Trogonidse,' which we 

 transcribe below. The range is now found to be a little more extended, as Arce sent 

 us an adult male from Veraguas, and we have adults of both male and female from the
