of Colombia, the abdomen is yellow to somewhat orange-yellow, and 

 the tail in the female has the white more prominent, especially at

When Deignan (U.S. Nat. Mns. Bull. 221, 1961, p. 190), in the 

 list of type specimens of birds in National Museum collections, noted 

 that the type of Trogon bairdii should have been labeled "Turrialba 

 (not San Mateo), Province of Cartago, Costa Rica" he copied a 

 notation on the card covering this bird in the Museum's species catalog. 

 This entry was an error, as the bird is one of the Pacific slope, and 

 Turrialba is on the Caribbean side. San Mateo, in southern Guana- 

 caste on the Pacific side is to be accepted as the correct locality.
