FAMILY DENDROCOLAPTIDAE I9 



front grayish brown, the rear surface pale dull brown ; toes dull 

 neutral gray ; claws dark neutral gray. 



Measurements. — Males (10 from Los Santos, Herrera, Panama, 

 and Darien), wing 74.0-80.4 (78.0), tail 67.4-74.2 (70.8), culmen 

 from base 16.1-17.8 (16.9. average of 9), tarsus 17.0-17.8 (17.3, 

 average of 9) mm. 



Females (10 from Los Santos, Herrera, Veraguas, eastern sector 

 of Panama, and Darien), wing 65.8-73.8 (70.7), tail 60.0-69.3 (64.2, 

 average of 9), culmen from base 15.2-17.2 (16.1), tarsus 16.0-17.5 

 (16.8) mm. 



Resident. Found locally in wooded areas on the Pacific side from 

 V^eraguas and the Azuero Peninsula east through Darien ; on the 

 Caribbean slope from northern Veraguas (Calovevora) and northern 

 Code (Cascajal) through the Canal Zone to western San Bias 

 (Mandinga). 



These woodcreepers frequent gallery forest where, because of 

 their quiet habits and inconspicuous coloration, they may be more 

 common than the scattered records indicate. Aldrich found them in 

 eastern Veraguas back of the Golfo de Montijo, from near sea level 

 to 900 meters in the inland mountains (Cerro Viejo). On the eastern 

 side of the Azuero Peninsula I collected one in the hills called Los 

 Voladores beyond Portobellilo in the Province of Herrera, and 

 another near Parita. On the Pacific side of the Canal Zone, J. R. 

 Karr banded one at Chiva Chiva, December 14, 1968. The Ameri- 

 can Museum of Natural History has a male collected by E. S. 

 Morton at Fort Kobbe, January 19, 1971. In my own work I have 

 found it most often from the southern side of Cerro Azul eastward. 

 Goldman collected two at 900 meters on Cerro Pirre, and I found 

 it at 1425 meters on Cerro Mali. On the Caribbean side Arce took 

 one at Calovevora, northern Veraguas (specimen now in the British 

 Museum), and there is one in the U.S. National Museum taken by 

 Heyde and Lux at Cascajal, northern Code, on March 13, 1889. On 

 March 1, 1952, I shot one at El Uracillo, farther east in Code, but 

 lost it in the dense ground cover. There have been no records for it in 

 the Chagres Basin in the northern Canal Zone or in adjacent Panama. 

 In February 1957, we saw two or three near Mandinga in the western 

 San Bias. 



Eugene Eisenmann reports their call as a thin high trill, accompanied 

 by shivering wings. Stomachs of two taken by (joldman on Cerro 

 Pirre were filled with broken bits of insects, largely remains of 

 fulgorids, but with parts of roach egg cases, ants, an ichneumon fly.
