440 BIRDS OF THE REPUBLIC OF PANAMA — PART 3 



In a female, from Juan Mina, Canal Zone, collected January 14, 

 1961, the iris was light brown; band across mandible anterior to 

 gonys brownish buff; rest of bill dusky neutral gray; gape dull buff; 

 tarsus and toes neutral gray ; claws fuscous. 



Measurements. — Males (10 from Canal Zone, Colon, Province of 

 Panama, Darien, and San Bias), wing 84.6-89.9 (87.7), tail 65.5- 

 71.5 (66.4), culmen from base 22.4-26.1 (24.5), tarsus 23.7-25.7 

 (24.5) mm. 



Females (10 from Canal Zone, Province of Panama, Darien, and 

 San Bias), wing 81.0-84.0 (82.4), tail 61.0-64.6 (62.8), culmen 

 from base 22.5-26.2 (24.0). tarsus 23.1-25.4 (24.1) mm. 



Weight, c^, 32 grams (G. V. N. Powell). 



Resident. Fairly common in the Tropical Zone from Code (El 

 Valle, El Uracillo), western Colon (Rio Indio), Cerro Campana, 

 and the Canal Zone eastward on both slopes to the Colombian bound- 

 ary ; to the lower Subtropical Zone on Cerro Tacarcuna and Cerro 

 Pirre. 



At Charco del Toro, on the lower Rio Maje, Darien, March 20, 

 1950, one flushed from a nest placed at the bottom of a narrow space 

 in a fork between two sections of a large tree that stood on the bank 

 of the river, the nest site a little over 2 meters above the ground. 

 The bird came off beside my head and dropped almost to the ground, 

 so that as it flew away I had clear view of it. The nest, a fairly deep 

 cup of dark rootlets, held three beautifully marked eggs, far advanced 

 in incubation. The two preserved are pinkish buff, marked heavily 

 with rather large, irregular spots of chocolate, mixed with cinnamon- 

 buff and lilac, mainly in a wreath around the large end but with a few 

 rather small in size scattered elsewhere. In form slightly pointed 

 subelliptical, they measure 26.0x20.0 and 27.8x20.0 mm. The 

 embryos had long down on head, dorsal, and crural tracts. 



The pajaro griton comes regularly with other birds to eat the 

 drupes of feeding trees. It also picks up many insects in gleaning 

 over branches and leaves, but I did not observe it capturing insects 

 on the wing. The well-filled stomach of one taken by Goldman, at 

 Portobelo, Colon, held two drupes of a species of Lauraceae, bits of a 

 cicada, two earwigs, and parts of a small lizard. A few bits of small 

 beetles also included may have come from the stomach of the lizard. 



Lawrence indicated that his type, collected by McLeannan and 

 Galbraith during the winter of 1860-1861, came from the Atlantic 

 slope near the line of the railroad. Hellmayr (Cat. Birds Amer., 

 pt. 6, 1929, p. 136) restricted the type locality to Lion Hill, which 

 was McLeannan's station.
