FAMILY TROGONIDAE 397 



inclusion of "Veraguas (Merritt)" as the collections of Dr. Merritt 

 were made on the Caribbean slope. The female described as that of 

 this species by Lawrence (Ann. Lye. Nat. Hist. New York, vol. 9, 

 1868, p. 119) from Costa Rica proved later to be a specimen of Trogon 

 bairdii (Salvin and Godman, Biol. Centr.-Amer., vol. 2, 1896, p. 497). 



Trogon clathratus is little known in Panama as collecting within its 

 range has been limited. The only recent specimen is a male taken 

 September 11, 1961, by R. Hinds, working under Dr. Pedro Galindo, 

 at a mountain camp at 800 meters on the Rio Changuena, Bocas del 

 Toro, in the headwaters of the Rio Changuinola. 



In Costa Rica, Carriker (Ann. Carnegie Mus., vol. 6, 1910, p. 563) 

 found the lattice-tailed trogon on the Rio Sixaola below Cuabre, across 

 the river from Panama. Dr. Paul Slud from his field notes informs 

 me that he has recorded the species from near that point to the 

 Caribbean slope of Volcan Tenorio in northwestern Costa Rica. His 

 interesting account (Bull. Amer. Mus. Nat. Hist., vol. 128, 1964, 

 pp. 165-166) is the only report to date of its habits. He found it — 



. . . from the lower tropical belt up to at least 4500 feet, with its 

 center of abundance following the foothills and slopes of the cordilleran 

 core of the country. Probably it reaches the lowlands in many places 

 along the fringing foothills. At any rate I found it not uncommon 

 under these circumstances in the Sarapiqui region. It is completely 

 sympatric with the wide-ranging, very similar, congeneric massena. . . . 

 This trogon is found almost exclusively in heavily wooded areas. 

 It is a true forest inhabitant that occurs only occasionally at the 

 forest border or beside it in the shaded semi-open, unlike the broadly 

 tolerant massena, and is met singly or as a somewhat separated member 

 of a pair. Its habits appear indistinguishable from those of massena in 

 most respects. Vocally, too, it resembles massena. Its usual call differs 



in being higher pitched .... than the barking notes of massena 



I would have expected sympatric species so much alike to have very 

 different voices. 



The light-colored eye is unusual in this family of birds. 



TROGON BAIRDII Lawrence: Baird's Trogon, Aurora de Baird 



Trogon bairdii Lawrence, Ann. Lye. Nat. Hist. New York, vol. 9, April 1868, 

 p. 119. (San Mateo, Costa Rica.) 



Medium size; male differs from other trogons with extensive red 

 under surface by its pure white outer tail feathers; female distin- 

 guished from other species with foreneck and upper breast entirely 

 slate-gray by the white bars on the tail.
