ing, other than frayed tail ends in some of the females. Stomachs 

 that I examined held berries, palm seeds, bits of the pendant flower 

 tassels of the guarumo (Cecropia), a walking stick, and other large 

 orthoptera. 



Countrymen along the Rio Chucunaque believed that to kill one 

 of these birds might bring bad luck. Dr. Jose Borrero told me that in 

 the middle Rio Magdalena in Colombia this trogon was called canario. 



It is interesting to find two sympatric species apparently so similar 

 as this one and the Massena trogon. A detailed comparative study of 

 the two in life should be of scientific interest.
