568 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



duller brown; tail blackish brown, with the outer rectrices paler, 

 browner ; wings brown, less tawny than the back, except the coverts, 

 which vary toward the dorsal color; side of head including loral 

 area grayish brown ; chin and upper throat gray, varying in depth of 

 color ; lower foreneck and upper breast dark brown ; rest of under 

 surface lighter, more tawny brown ; under wing coverts grayish 

 brown; inner webs of wing feathers with broad spots or bars of white. 



Adult female, like male, but with crown feathers tipped with 

 brown, the feathers being dusky basally. 



Immature male, red of crown duller, usually restricted to distal 

 two-thirds. 



A female, taken on Cerro Mali, Darien, February 27, 1964, had 

 the iris warm brown ; maxilla, except area below the ridge above the 

 nostril, and the distal end of the mandible, dull black ; rest of maxilla 

 and base of mandible neutral gray shading on the mandible through 

 neutral gray to the darker color of the tip ; tarsus and toes dull dark 

 neutral gray; claws black. 



Measurements. — Males (11 from Costa Rica, Chiriqui, and Vera- 

 guas), wing 84.7-89.9 (87.3), tail 45.6-55.3 (50.6, average of 10), 

 culmen from base 20.7-24.2 (22.0), tarsus 16.9-18.8 (18.1) mm. 



Females (9 from Costa Rica, Chiriqui, and Veraguas), wing 85.4- 

 88.0 (85.8), tail 46.7-51.5 (49.1), culmen from base 19.0-23.2 (21.0), 

 tarsus 17.1-18.1 (17.7) mm. 



Resident. Rather rare in the upper Tropical and Subtropical Zones 

 in mountain areas from western Chiriqui, across the divide into 

 adjacent Bocas del Toro, and east to Veraguas; also on Cerro 

 Tacarcuna, Darien (there somewhat intermediate toward nominate 

 fumigatus of Colombia). 



Most of the records for this little known bird have come from 

 the western side of the great volcano west to the boundary with Costa 

 Rica. There I have found it, usually in pairs, in the borders of 

 clearings in the forest, and in shade trees over coffee plantations. 

 The birds move quietly, and with their dull coloration are difficult to 

 find. Rarely I heard one utter a low call, and occasionally my atten- 

 tion was drawn by their tapping as they moved over the trunks of 

 the trees. They seem to prefer smaller tree trunks to larger ones, 

 so that second growth — the rastrojo — is attractive. 



Mrs. Davidson Terry collected the first specimens in this general 

 area at Barriles, near the Rio Chiriqui Viejo, in January 1931. Blake 

 (Fieldiana: Zool., vol. 36, 1958, p. 527) found only one in the
