limit for the species, it having come down the Pacific lowlands from 

 Nicaragua, and into the Nicoya peninsula. It has been reported in 

 eastern Nicaragua, but I have never seen it in northeastern Costa Rica ; 

 this, however, would be true melanocephalus, the new form being con- 

 fined to the Pacific slope of Nicaragua as well as Costa Rica. In 

 habits it is very like T. atricollis, inhabiting the forest, rather 

 low down in the trees, and not being at all shy like puella or under- 



woodi.

Costa Rican birds compared with specimens from Guatemala and 

 British Honduras are indistinguishable. 



This is the most abundant and widely spread of all the trogons of 

 Costa Rica, ranging over practically the whole of the country up to 

 nearly 4,000 feet, but always more abundant at lower altitudes, that 

 is, below 2,000 feet on the Caribbean slope and below 1,000 feet on 

 the Pacific. It is found in the forest as well as in open woodlands 

 and isolated clumps of trees, but is perhaps more partial to wooded 

 pastures and other similar localities. It is usually quite tame and 

 easily approached.
