54 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



A male shot on Cerro Mali, Darien, February 22, 1964, had the iris 

 orange, edge of eyelids, a spot in front of the eye, and gape dull red ; 

 bare loral area dark neutral gray ; bill and cere black ; tarsus and toes 

 dull red ; claws dull grayish brown. 



Measurements. — Males (10 specimens), wing 138.2-148.2 (145.1), 

 tail 84.5-90.0 (88.5), culmen 13.2-16.7 (14.8), tarsus 38.4-45.3 (41.2) 

 mm. 



Females (7 specimens), wing 138.8-145.7 (143.0), tail 83.8-90.8 

 (86.5), culmen 14.0-16.9 (15.5), tarsus 38.0-42.7 (40.7) mm. 



Resident. Local in Tropical and Subtropical Zones in the mountain 

 forests of Darien ; recorded from Cerro Sapo, at 900 meters ; Cerro 

 Pirre, from 900 to 1,600 meters; Cerro Tacarcuna and Cerro Mali, 

 at 1,450 meters. 



This was one of the new birds collected by E. A. Goldman in 1912 

 on the higher slopes of Cerro Pirre. He found it common, and in 

 April heard its call near his camps throughout the day — a hollow 

 cooing sound like that made by blowing in a bottle. His first specimen 

 was shot from a treetop, but all others were found on the forest floor, 

 where they walked aside when approached. Dr. Pedro Galindo col- 

 lected 2 here on August 9, 1965. 



The stomach of one of Goldman's specimens was filled with seeds, 

 most of them broken, some of rather large size. With them the bird 

 had swallowed a small stone that measured 16 by 7 mm., with a 

 thickness of 3% mm. 



On the Colombian slopes of the Tacarcuna range in the Choco, 

 Harold E. Anthony collected specimens on the headwaters of the Rio 

 Cuti on March 29, April 1, and April 10, 1915. De Schauensee 

 (Acad. Nat. Sci. Philadelphia, Not. Nat., no. 144, Oct. 13, 1944, 

 p. 4) has recorded a young bird, not fully grown, from the low 

 elevation of 90 meters on the Rio Jurado, Choco, Colombia. 



Three were collected by the party from the Gorgas Memorial Labo- 

 ratory on Cerro Mali on May 27, 31, and June 4, 1963, and I secured 

 another here February 22, 1964. The birds ranged across Cerro Mali 

 and the slopes of Cerro Tacarcuna in company with Geotrygon I. 

 lawrencii, but were less common. I saw them occasionally walking 

 quietly in the dark shadows of the forest undergrowth, and recorded 

 them also by their calls. These, heard usually in early morning, were 

 a curious sound, quite different from the croaking of G. lawrencii, 

 well characterized by Goldman's description of air blowing over the 

 mouth of a bottle.
