BIRDS OF THE REPUBLIC OF PANAMA PART 4 



pallidi pectus; more or less intermediate between that form and 



bulunensis. 



A male taken February 22, 1963, at Armila, San Bias, had the iris 

 grayish white; maxilla black; mandible neutral gray; tarsus and toes 

 bluish dark neutral gray. 



Measurements. — Males (7 from Veraguas, Province of Panama, 

 Canal Zone, and San Bias), wing 54.5-57.0 (56.1), tail 37.9-45.8 

 (40.5), oilmen from base 13.5-14.5 (13.9), tarsus 15.1-16.5 (15.9) mm. 



Females (6 from Veraguas, Province of Panama, Canal Zone, and 

 San Bias), wing 53.0-58.3 (55.6), tail 39.4-42.3 (40.7), culmen from 

 base 12.2-15.2 (13.5), tarsus 15.1-17.0 (16.4) mm. 



Resident. Griscom (Bull. Mus. Comp. Zool., vol. 78, 1935, p. 365) 

 lists nelsoni from the "Pacific slope, coastal forests of Veraguas to 

 Rio Chepo, Darien [= Province of Panama]; rare." I have collected 

 this race beyond Griscom's limits, at Cerro Chucanti (300 m), in the 

 Serrania de Maje, eastern Province of Panama, and at Armila, San 

 Bias. The Smithsonian also has specimens from Lion Hill and from 

 between Summit Gardens and Gamboa in the Canal Zone, and from 

 Chepo, Province of Panama. The Havemeyer collection, now in the 

 Peabody Museum at New Haven, contains a male collected at Puerto 

 San Antonio, on the Rio Chepo. 



E. A. Goldman's notes for May 1, 1911, when he was at Lion Hill, 

 include the following: "A pair of these was seen and shot among low 

 limbs of trees and rather thick jungle in fairly heavy forest. They were 

 about 10 feet from the ground and were killed only about 15 feet apart. 

 . . . They showed no breeding signs. Apparently a rare forest species." 

 The pair I found at Armila was caught in a mist net set in heavy forest, 

 and 2 that I took at Cerro Chucanti were in tall tree tops. 



The American Museum collection contains a female (783985) col- 

 lected January 23, 1964, by F. L. Chapman and E. Tyson in the Canal 

 Zone 9.7 km north of Gamboa (Pipeline Road, Limbo Hunt Club) that 

 contained an egg in the oviduct.
