FAMILY PICIDAE 537 



Measurements. — Males (11 from Costa Rica and Panama), wing 

 105.5-114.2 (109.6), tail 57.0-62.0 (59.6), oilmen from base 20.0- 

 23.7 (21.9), tarsus 17.0-19.3 (18.0) mm. 



Females (6 from Costa Rica and Panama), wing 104.0-114.0 

 (109.9), tail 54.8-61.2 (59.1, average of 5), culmen from base 21.1- 

 22.7 (21.7), tarsus 17.9-19.4 (18.6) mm. 



Resident. Rare in the lowlands of western Chiriqui, western Bocas 

 del Toro, and the Caribbean slope of Veraguas, near the Rio 

 Calovevora. 



Arce collected the type specimen, a female, at Bugaba in 1869, 

 and later secured another of the same sex, marked only as from 

 Chiriqui. These are the only records from the Pacific slope. Hargitt 

 (Cat. Birds Brit. Mus., vol. 18, 1890, p. 81) through an evident 

 error listed this second specimen as the type. The species was recorded 

 next in the Republic in Bocas del Toro, when on February 11, 1926, 

 F. H. Kennard collected a male on Western River near Almirante 

 (Kennard and Peters, Proc. Boston Soc. Nat. Hist., vol. 38, 1928, 

 p. 454). Later in the same year R. R. Benson and Lieutenant Dale V. 

 Gaffney found the species near the Rio Calovevora on the Caribbean 

 slope of northern Veraguas (Griscom, Amer. Mus. Nov., no. 280, 

 1927, p. 2). Benson subsequently collected others near Almirante, 

 Bocas del Toro. Griscom described a subspecies from these under 

 the name aurorae, which later proved invalid. 



Beyond Panama this species is found through Costa Rica to 

 Nicaragua. Slud (Amer. Mus. Nat. Hist., Bull. 128, 1964, p. 188) 

 describes the call as resembling that of the golden-olive woodpecker 

 but "more drawn out and descends with weakening intensity as it 

 finishes." While he notes the iris as "sky-blue," Kennard (cit. 

 supra) recorded in a male that the eye was white. 



PICULUS LEUCOLAEMUS CALLOPTERUS (Lawrence): 

 Stripe-cheeked Woodpecker, Carpintero de Mejilla Rayada 



Chloronerpes callopterus Lawrence, Ann. Lye Nat. Hist. New York, vol. 7, 1862, 

 p. 476. (Atlantic side, line of the Panama Railroad = Caribbean slope, Canal 

 Zone, Panama.) 



Similar to the rufous- winged woodpecker, but throat barred, and 

 a white streak on the side of the head. 



Description. — Length 165-180 mm. Adult male, feathers of crown 

 and hindneck tipped with red, with the gray bases visible irregularly ; 

 back, scapulars, outer webs of secondaries and lesser to greater
