FAMILY TROGLODYTIDAE

in the zone only in the very humid forested northwestern area along 

 the Achiote Road. 



This species is locally fairly common, but comes to attention mainly 

 from its calls, as usually the birds move about under cover of leaves. 



A female, taken by E. A. Goldman at 850 m near Cana, May 22, 1912, 

 had the stomach filled with insect remains that included chrysomelid 

 and tenebrionid beetles, orthoptera, and ants. Three males collected by 

 Strauch (Bull. Brit. Orn. Club., 1977, p. 64) in the Province of Pan- 

 ama and Canal Zone weighed 32.7, 34.0, and 34.3 g. 



Eisenmann (in litt.) found a group of 3 or 4 on the Achiote Road 

 on March 23, 1967, in shady, canopied, damp second growth ranging 

 in the foliated trees from 5 to 20 m and giving harsh notes like churk 

 or kurk. An unseen bird uttered a harsh song ending with semimusical 

 kaw notes. At Altos de Maje above Rio Bayano, eastern Province of 

 Panama, Eisenmann found 3 wrens on the ground, dust bathing in the 

 forest; while dust bathing they were at times in physical contact. 



CAMPYLORHYNCHUS ALBOBRUNNEUS HARTERTI (Berlepsch) 



Heleodytes harterti Berlepsch, Ornis., vol. XIV, February 1907, p. 347. (San Jose, 

 Rio Dagua, Valle, Colombia.) 



Characters. — Feathered area of the lower leg (the tibia) with the 

 markings definitely darker; undertail coverts duller white, heavily 

 spotted and barred with dull grayish brown; immature, with brownish 

 gray lines and feather borders on the crown and side of head more 

 abundant, so that this area is darker. 



Measurements. — Males (10 from eastern San Bias, and adjacent 

 Colombia, in Choco and Antioquia), wing 81.5-88.2 (85.3), tail 75.2- 

 82.1 (79.5), culmen from base 22.5-27.4 (24.8), tarsus 25.5-28.1 

 (26.6) mm. 



Females (9 from eastern San Bias and adjacent Colombia, in Choco 

 and Antioquia), wing 76.0-82.5 (78.7), tail 72.7-82.5 (77.6), culmen 

 from base 21.9-24.4 (23.3), tarsus 23.7-27.0 (24.7) mm. 



Resident. On the Caribbean slope, in eastern San Bias (Puerto 

 Obaldia). The first record of this darker form was by Griscom (Bull. 

 Mus. Comp. Zool., vol. 72, 1932, p. 358) of a female collected by von 

 Wedel at Puerto Obaldia (date not listed). In the Museum of the 

 University of Cincinnati there are 2 others, male and female, taken by 

 Wedel at this locality August 28, 1931. 



It is possible that this race is found along much of the coast of San 

 Bias, though recorded at present only at the eastern end. It is common
