FAMILY PICIDAE 535 



gonys dusky neutral gray ; tarsus and toes neutral gray ; claws brown- 

 ish gray. 



Measurements. — Males (10 from Chiriqui and Veraguas), wing 

 117.2-123.8 (120.1), tail 61.0-70.0 (65.9), culmen from base 25.6- 

 29.0 (27.1), tarsus 20.5-23.6 (21.9) mm. 



Females (11 from Chiriqui, Veraguas, and Code), wing 116.5-121.8 

 (119.2), tail 64.2-71.3 (68.6), culmen from base 23.7-27.4 (25.5), 

 tarsus 20.0-22.2 (21.0) mm. 



Resident. Mainly from 1,250 to 1,675 meters elevation in the 

 Subtropical Zone in Chiriqui and Veraguas; also in the Tropical 

 Zone in dense rain forest in northern Code. 



This woodpecker is fairly common around the volcano in western 

 Chiriqui, ranging there in the Subtropical Zone above Boquete, near 

 El Volcan, at the lakes, and on the slopes of Cerro Pando, farther 

 west. 



Dr. C. L. Hayward secured a male March 9, 1962, near Cerro 

 Punta, and Dr. Frank Hartman another near Santa Clara to the west 

 February 28, 1953. (Both birds are now in U. S. National Museum.) 

 Arce collected it a hundred years ago on the Cordillera del Chucu, 

 Veraguas, a locality near Santa Fe (specimens in the British Mu- 

 seum). On February 26, 1962, I shot a female at my camp in the 

 clearing El Tigre at 475 meters on the head of the Rio Guabal, on 

 the Caribbean slope of Code. The region was one of dense forest and 

 heavy rainfall. Salvin and Godman (Biol. Centr.-Amer., Aves, vol. 2, 

 1895, p. 407) recorded specimens taken by Arce at Calobre, Veraguas, 

 and Bibalaz, Chiriqui, both lowland localities, formerly heavily for- 

 ested. While the species normally is found in such haunts it also 

 comes regularly into more open areas, even in fairly low second 

 growth. 



Skutch, in observations in Costa Rica (Wilson Bull., 1956, pp. 118- 

 128), describes the drum of the male as a loud, rapid roll. A nest 

 that he found April 5, in a hole in a dead stub about 4 meters from 

 the ground held 4 glossy white eggs. The male incubated at night, 

 with the female sleeping elsewhere. The pair alternated in these 

 duties during the day. The newly hatched young were completely 

 naked. Only 1 young bird was brought to maturity in this nest. 



Belcher and Smooker (Ibis, 1936, p. 797) list measurements of 

 4 eggs of the slightly smaller race Piculus rubiginosus trinitatis 

 from Trinidad as 24.5-26.0 X 18.7-19.3 mm. Two other eggs collected 

 by Belcher at Macquarie, Trinidad, now in the British Museum 

 (Natural History) that I have examined, are slightly smaller, with
