258 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



and blotched with deep or pale chestnut, forming a more or less distinct 

 cap on the broader end." Three weeks after discovery, the nest con- 

 tained 3 well- feathered nestlings in the entrance; both parents were 

 bringing them green caterpillars, a small, green, grasshopper-like in- 

 sect, and tiny white protein corpuscles from a Cecropia tree. 



Ridgely (in litt.) reports that on June 7, 1969, he found a nest near 

 El Volcan. It was on the underside of a moss-covered limb, "burrowed 

 into the moss," about 10 m up in a roadside tree, in a patch of humid 

 woodland, 5.1 km below El Volcan, on the highway. Some grass and 

 twigs projected from the nest. 



PARULA PITIAYUMI CIRRHA Wetmore 



Parula pitiayumi cirrha Wetmore, 1957, Smiths. Misc. Coll., 134 (9), p. 88. (Isla 

 Coiba, Panama.) 



Characters. — More deeply colored above and below than P. p. spe- 

 ciosa; green patch on back very small; sides of face blackish-blue; 

 throat lemon chrome; lower breast and abdomen orange, continuous 

 with chest color; conspicuous white spot on greater wing coverts. 



Measurements. — Males (4 from Isla Coiba), wing 52.4-58.5 (55.8), 

 tail 39.2-41.7 (40.8), culmen from base 12.1-12.8 (12.5), tarsus 15.7- 

 17.8 (16.8) mm. 



Females (2 from Isla Coiba), wing 53.5-54.7 (54.1), tail 39.2-39.8 

 (39.5), culmen from base 11.7-12.6 (12.2), tarsus 16.7-16.8 (16.8) 

 mm. 



Resident on Isla Coiba. On three occasions during my visit to Isla 

 Coiba in 1966 I saw pairs of these birds moving quickly among leafly 

 twigs in the high branches of tall forest trees, so high above the ground 

 that they were barely within gunshot. Except for their restless move- 

 ments they would never have been detected in the shaded light of these 

 forest haunts. Only occasionally did they appear briefly in silhouette 

 against some tiny opening that led to the open sky. Probably they were 

 fairly common, as the forest cover of the entire great island was suited 

 to their needs. 



During a short stay (October 8-10, 1965) Eisenmann and E. S. 

 Morton found the Coiba birds common in all woodland, usually in pairs 

 between 1 and 8 m up in trees, on the border of woods or partly cut- 

 over forest. None were singing. On Ridgely's visit (April 9-14, 1976) 

 he found the birds singing very persistently and saw them at all levels 

 in the forest.
