FAMILY TROGONIDAE 405 



webs of secondaries, and greater, middle, and lesser coverts (except 

 the anterior rows), lined narrowly and irregularly with white; a 

 femoral tuft on either side white basally, red distally ; forehead, side 

 of head and throat black ; foreneck and upper breast metallic green to 

 golden green ; a prominent white band across center of breast, with 

 the uppermost feathers basally black ; sides gray, banded slightly and 

 indistinctly with black ; rest of under surface geranium red ; tibia and 

 feathers of upper half of tarsus black ; under wing coverts dark gray, 

 tipped lightly with white; bases of inner primaries and secondaries 

 white. 



Adult female, above brown, darker on the crown, somewhat more 

 rufescent on the rump and upper tail coverts ; middle pair of rec- 

 trices chestnut tipped with black ; next two pairs black on inner 

 web, chestnut on outer web ; three outer pairs black on dorsal surface, 

 grayish underneath, tipped with white, with a narrow subterminal 

 bar of black; outer webs edged with white, freckled with gray, nar- 

 rowly toward base, broadly distally; wings slaty black, the longer 

 primaries edged with white ; outer webs of secondaries, and greater, 

 middle, and lesser coverts brown, minutely lined and freckled with 

 dusky ; a white eye-ring broken and indistinct anteriorly, broad 

 on posterior margin ; side of head slaty black ; throat grayish slate ; 

 upper breast and sides brown like back ; a broad white breast band, 

 but without the black upper border found in the male ; rest of under 

 surface as in male. 



The collared trogon is found from southern Mexico through 

 Central America and South America (including Trinidad and To- 

 bago) south to Peru, Bolivia, and southern Brazil (not recorded to 

 date from Surinam). Though eight geographic races have been recog- 

 nized in this area all are closely similar in general appearance. Three 

 of these are found in the Republic. Males of the several subspecies 

 of South America and the population of Cerro Pirre in eastern 

 Darien have the white tip of the three outer rectrices from three to 

 six times wider than any of the white bars on the upper part of 

 these feathers. In adult males of the wide ranging subspecies puella, 

 and the local race of the Tacarcuna region in Panama, this terminal 

 white tip is only slightly broader than those adjacent above. How- 

 ever, the young male in first adult dress of these more northern 

 birds has this marking broad as in the southern group, an apparent 

 relict character that has disappeared in the adult.
