FAMILY TROGONIDAE 407 



this trogon would not be found. Their reports for Calovevora and 

 Cordillera de Tole refer to Trogon aurantiiventris. A record for 

 Isla Gobernadora in the lower Golfo de Monti jo, on the Pacific 

 coast of Veraguas (Auk, 1950, p. 364), is based on a specimen with 

 false locality forwarded by J. H. Batty to Lord Rothschild. 



The bird is one of forests that may range in fairly open areas as 

 well as in the denser sections. Usually I have found them in pairs. 

 An ordinary call is cow cow, repeated steadily and rather slowly. Also 

 they utter a plaintive double- or treble-noted whistle easily imitated, 

 through which on several occasions I have decoyed the birds close 

 to me. In tone this call suggests that of some of the antshrikes, 

 tropical ovenbirds, or other small bush inhabitants, quite different from 

 any other sound that I have heard from a bird of this family. On 

 occasion I have had them fly to a perch above me with rattling wings, 

 and peer down with curiosity as I moved about slowly in undergrowth. 



Five nests recorded by Rowley (Proc. West. Found. Vert. Zool., 

 Vol. 1, No. 3, 1966, p. 152, fig. 29) in the Sierra Madre del Sur, 

 Oaxaca, each held 2 slightly glossy white eggs, with range in size 

 27.3-31.7x22.9-23.5 mm. An egg in the British Museum, from 

 Irazu, Costa Rica, with date of May 18, 1900 (collector not given 

 but handwriting on original label apparently that of C. F. Under- 

 wood) is dull white, without gloss, in form short subelliptical. It 

 measures 27.7x21.9 mm. 



As Gould, in his description of paella listed his specimen from 

 "Escuintla, South America" some have considered the country as 

 uncertain, since the name is found in Mexico and elsewhere. There 

 seems to be no reason to doubt that the bird came from Guatemala. 



TROGON COLLARIS HEOTHINUS Wetmore 



Trogon collaris heothinus Wetmore, Proc. Biol. Soc. Washington, vol. 80, 

 December 1, 1967, p. 238. (North Fork of Rio Pucro, Cerro Tacarcuna, 

 2000 meters elevation, Serrania del Darien, Darien, Panama.) 



Male similar to that of T. c. puella, but with white bars on tail 

 broader, more prominent; female duller, more grayish olive-brown, 

 on upper surface and breast. 



A male, collected February 20, 1964, on Cerro Mali, Darien, had 

 the iris dark brown ; bill yellow, verging toward honey yellow ; tarsus 

 and toes light brownish gray ; claws fuscous. 



A female, taken February 27, in the same area, had the iris wood 

 brown; side of maxilla from base below and back of nostril, forward
