FAMILY FRINGILLIDAE 



577 



tern of distribution common to a number of other species, whereby a 

 northern, usually darker, form extends into Panama only along the 

 western Caribbean coast and is replaced elsewhere in the country by a 

 different subspecies that may extend into southwestern Costa Rica. On 

 February 1, 1958, I collected a male at Almirante in brown plumage 

 showing no signs of molt; it had the testes half enlarged toward breed- 

 ing. Pedro Galindo has found nests at Almirante on May 23 and 30, 

 1962, but neither contained eggs. Skutch (Auk, 1945, p. 24) lists the 

 incubation period at Almirante as 12 days and the nestling period as 

 from 10 to 12 days. 



SPOROPHILA ANGOLENSIS OCHROGYNE Olson 



Sporophila angolensis ochrogyne Olson, 1981, Proc. Wash. Biol. Soc, vol. 94(1), 

 p. 47. (Utive, Rio Calobre, Panama.) 



Characters.—- Females and subadult males paler than any other sub- 

 species of the funerea group, underparts deep buffy, not chestnut; 

 brown of breast and upperparts suffused with a grayish olivaceous 

 wash, not reddish, and much lighter than in other forms. 



A male collected at El Cope, Code, on February 23, 1962, had the 

 iris dark reddish brown; maxilla and tip of mandible fuscous-black; 

 base of mandible fuscous; cutting edge of maxilla dull brownish white; 

 tarsus and toes fuscous; claws fuscous-black. A female taken at Isla 

 Cebaco, Veraguas, on January 16, 1965, had the iris dark brown; 

 maxilla, except cutting edge at extreme tip, fuscous-black; rest of 

 maxilla and mandible fuscous-brown; tarsus and toes dark neutral 

 gray; claws dusky neutral gray. 



Measurements. — Males (10 from Panama), wing 55.3-58.3 (56.9), 

 tail 47.0-51.8 (49.1), culmen from base 12.5-14.0 (13.3), tarsus 15.0- 

 16.4 (15.8) mm. 



Females (10 from Panama), wing 52.1-58.0 (55.4), tail 48.1-52.0 

 (50.2), culmen from base 13.1-15.2 (13.9), tarsus 14.8-16.7 (15.8) 

 mm. 



Resident. Fairly common in the lowlands on both slopes of central 

 Panama, excluding the range of salvini, on the Caribbean side to Man- 

 dinga, San Bias, where I collected an immature male in 1957, and on 

 the Pacific side mainly from Veraguas through Darien. There are sev- 

 eral recent Darien reports, all from 1978 or later, from El Real and 

 vicinity, along the air strip at Cana, and near Pucro; Ridgely {in lift.) 

 believes the species is increasing in Darien with clearing of forest. In
