BIRDS OF THE REPUBLIC OF PANAMA PART 4 



2 males of this wren from Zegla, Rio Teribe, collected May 16, 1927. 

 The locality was a small village located near the mouth of the Rio 

 Teribe, where that stream enters the Rio Changuinola, about 4 km above 

 the bridge on the railroad, north of Almirante. It appears that Wedel, 

 cited above, either accompanied Smith or acquired one of his specimens. 



Our collections also include 2 skins of T. thoracicus, collected Sep- 

 tember 8 and 14, 1961, by Pedro Galindo at a camp at 750 m elevation 

 on the Rio Changuena, a tributary of the Rio Changuinola farther in- 

 land. There is no other report from the well-known Almirante area. 



Another record for the Caribbean slope is an adult dated March 3, 

 1889, marked Cascajal, Code, collected by the missionaries H. F. Heyde 

 and Ernesto Lux. The locality is on the Rio Cascajal on the Caribbean 

 slope in northwestern Code. 



In the American Museum of Natural History are 9 specimens labeled 

 from Guaval, Rio Calovevora, Veraguas (266-500 m), taken by R. R. 

 Benson between August 1-September 19, 1926. This river forms the 

 boundary between Bocas del Toro and Veraguas. One specimen from 

 September 4 is a full-grown bird in juvenal plumage. 



E. O. Willis (Eisenmann, in litt.) reports seeing a pair in September 

 1963 in the northwestern Canal Zone near the Caribbean coast on the 

 road to Rio Medio, following army ants. He writes that the vocalization 

 consisted mainly of single, similar notes somewhat resembling a Night- 

 ingale Wren but repeated more rapidly and sometimes varied with notes 

 of other pitches of a more Thryothorus quality. Pujals also reports 

 having once seen this species along the Achiote Road of the northwest- 

 ern Canal Zone, and later on February 14, 1947, near Rio Indio village 

 in western Colon. 



A record by Salvin (Proc. Zool. Soc. London, 1867, p. 134) re- 

 ports 3 specimens received from Arce, erroneously as from "San- 

 tiago de Veragua," far down in the Pacific lowlands of Veraguas. 

 This error was repeated by Salvin and Godman (in Biol. Centr.-Amer., 

 Aves, vol. 1, 1880, p. 86). The bird is known in Panama almost ex- 

 clusively from the Caribbean slope, and so may have been taken in the 

 Calovevora area on the northern Caribbean slope of the mountains, ac- 

 cessible by a well-known trail from Arce's permanent location at Santa 

 Fe. On March 18, 1974, Skutch and Eisenmann (in. litt.) heard the 

 distinctive call of this species in the humid forest on Santa Fe, on the 

 Pacific slope. Evidently the bird does cross the Divide in at least this 

 location. 



Arce, in the early days of his work in Panama, seems not to have 

 labeled some of his specimens carefully. Salvin, with the lack of detail
