FAMILY DENDROCOLAPTIDAE II 



(Boquete, El Volcan) ; one record for adjacent Bocas del Toro (on 

 the upper Rio Changuena) . 



These birds seem never to have been very common, and as forests 

 have been cleared have decreased in number through this curtailment 

 in their habitat. In several seasons in both the mountain area and 

 the lowlands in Chiriqui I have encountered them on two occasions 

 only, both near the Rio Chiriqui Viejo west of El Volcan. 



The type specimen, in the U.S. National Museum, a bird received 

 from Osbert Salvin in 1872, has printed on the label "Collected by 

 Enrique Arce Veragua" with the locality "Chiriqui" added by hand. 

 Salvin (Proc. Zool. Soc. London, 1870, p. 177) wrote that Arce's 

 Chiriqui collections of the period concerned "were formed on the 

 southern slope of the Volcano" with Mina de Chorcha, Bugaba, and 

 Volcan de Chiriqui as the localities. It seems probable that the speci- 

 men came from the area bounded by Bugaba and Boquete so that it is 

 appropriate to list the type locality as the southern slope of the 

 volcano.

Resident. Found locally on the Pacific slope from eastern Chiriqui

 Province of Panama, the Canal Zone, and Darien. 



The most western record is of male and female collected by 

 Griscom and Boulton on Cerro Flores in eastern Chiriqui. Others 

 from Veraguas come from the lower slopes below Santa Fe, and 

 from Cerro Montuosa in the northern end of the Azuero Peninsula.
