l62 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



Found in low, dense thickets in high forest on Silla de Cerro Pando, 

 they were always secretive and difficult to see. Occasionally, I heard 

 them give low, mewing, sometimes trilling calls. One (prepared as a 

 specimen) was captured lower down in a mist net set near the Rio 

 Chiriqui Viejo. Two birds in juvenile dress, fully grown, were taken 

 by S. L. Olson and K. Blum at Bambito, at about 1600 m, July 3, 1966. 



Blake (Condor, 1956, p. 388) described a nest in the Monniche col- 

 lection from Lerida, Chiriqui, as located 2.5 m above the ground in a 

 small tree, a compact structure of moss, much like that of the Black- 

 faced Solitaire, but with a few bits of dried leaves and plant stalks 

 woven into its base and sides. The cup, neatly lined with black hairlike 

 rootlets, had outside dimensions of 5y 2 x4 J / 2 x3 inches, with the cup 

 2^2 X \ inches. The single egg preserved, pale greenish white, thickly 

 and almost uniformly speckled with light reddish brown, measured 

 23.4x17.3 mm. The collector's field notes state that the second egg, 

 similar in color, measured 23 X 18 mm.

Characters. — Upper surface paler; crown grayer; back lighter 

 brown; breast and sides lighter gray. 



A female collected at El Cope, on the Pacific slope of the Province of 

 Code had the iris dark brown; edges of eyelids and bill orange, with 

 the culmen dark neutral gray; tarsus and toes light orange; claws light 

 brown. 



Measurements. — Males (10 from Chiriqui and Veraguas), wing 

 72.5-82.5 (78.3), tail 55.5-62.0 (55.8, average of 9), culmen from base 

 15.1-17.8 (16.5), tarsus 28.5-31.3 (30.2) mm. 



Females (9 from Chiriqui, Veraguas, and Code), wing 73.5-82.5, 

 tail 54.6-62.5 (59.5), culmen from base 13.1-18.6 (16.1), tarsus 29.5- 

 31.7 (30.6) mm. 



Resident. Found locally in Chiriqui (Chame, Barriles, San Felix), 

 Veraguas (Sona, Sante Fe) and Code (El Cope). 



Near San Felix I found them in a small tract of forest near the Rio 

 San Felix, and near the coast in the area called Macano, also in forest. 

 At El Cope, on February 25, 1962, in the hills on the Pacific side, the 

 one taken was in heavy undergrowth in a small tract of forest. 



Eisenmann (in litt.) saw the species singing above Santa Fe, Vera- 

 guas, at approximately 750 m, near the Agricultural School, on March 

 28, 1974.
