FAMILY PICIDAE 569 



Monniche collection, a bird taken at Pena Blanca at 1,900 meters, 

 above Boquete. Bangs (Proc. New England Zool. Club, vol. 3, 1902, 

 p. 34) recorded a male collected by W. W. Brown, Jr., at 2,130 

 meters elevation on the Caribbean slope of the volcano in Bocas del 

 Toro, north of Boquete. Salvin and Godman (Biol. Centr.-Amer., 

 Aves, vol. 2, 1895, pp. 439-440) list one taken by Arce at Bugaba. 

 Other specimens from Arce are males reported by Salvin (Proc. 

 Zool. Soc. London, 1867, p. 157, and 1870, p. 212) from the Cordillera 

 de Tole, Chiriqui, and Cordillera del Chucu, near Santa Fe, Veraguas, 

 this being the eastern limit in western Panama. 



On the spur of Tacarcuna known as Cerro Mali, I found this 

 woodpecker in small numbers through the rather open forest. My 

 attention was drawn to them by their drumming, the usual rattle, 

 but one extremely rapid, apparently near the maximum speed possible 

 for this form of percussion. In skinning my only specimen I noted 

 that the submaxillary gland was small as it measured only 8 mm. 

 long by 2 mm. in diameter. As usual in this genus, feathers of the 

 head were loosely attached so that many sloughed away in spite of 

 care in skinning. 



Earlier, the Harold Anthony party had taken 1 lower down at the 

 old village site on the Rio Tacarcuna at 575 meters, on March 27, 

 1915, and 2 on the eastern, Colombian slope of the mountain at the 

 head of the Rio Cuti, Choco, on April 3 and 16, 1915. 



As a species this woodpecker ranges in mountain areas from eastern 

 Mexico to western Panama ; and from eastern Darien across Colombia 

 and Venezuela, south in the Andes to Bolivia and northwestern 

 Argentina. The nominate race, widely distributed in the mountains 

 of Colombia, is similar in color to sanguinolentus of Central America, 

 but differs in larger size, as shown in the following tabulation. 



Males (10 from Colombia), wing 92.3-100.4 (96.3), tail 49.6-54.6 

 (52.0), culmen from base 19.6-23.9 (21.9), tarsus 18.1-20.9 (19.1) 

 mm. 



Females (10 from Colombia), wing 93.0-101.0 (96.7), tail 46.6- 

 57.1 (52.4), culmen from base 21.2-23.5 (22.2), tarsus 18.3-19.8 

 (19.1) mm. 



In the few seen from Darien the wing in 3 males ranges from 

 88.7 to 91.7 mm., and in 1 female it is 90.3 mm. They show a 

 tendency in size toward the Colombian group, but appear nearer 

 sanguinolentus, in spite of their wide separation geographically.
