FAMILY TROGLODYTIDAE 



ruary 26 and March 5, 1976, Ridgely found it common at all elevations) , 

 Veraguas (above Santa Fe along Cerro Tute ridge, 1050 m, January 5, 

 1974), and probably even in western Province of Panama (at the very 

 top of Cerro Campana, ca. 1000 m, seen by N. G. Smith on September 

 7, 1968). 



Eisenmann has frequently seen it in humid montane forest from the 

 lake near El Volcan, ca. 1200 m, to well above Cerro Punta, close to 

 2400 m, and also on the Boquete side above Finca Lerida. They gen- 

 erally glean over vines and similar epiphytic vegetation on forest trees, 

 usually in pairs, creeping vertically along hanging lianas, but occas- 

 ionally even up tree trunks. Ridgely (in litt.) notes that this species 

 is a rather frequent member of mixed flocks including warblers and 

 tanagers. 



Eisenmann noted a semi-musical trilled tswee-tswee seeerrrr, also a 

 seeerrrrr alone, lasting about one second, sometimes drier as whirrrrr, 

 and a short, nonmusical srr or srrrrr or trrrr, which is perhaps the call. 



On April 26, 1961, on Martyn's Finca in the still forested, but logged 

 over area, Eisenmann saw pairs actively singing and displaying. One 

 bird landed on a vertical trunk and sang with shivering wings; another 

 carried nesting material. Still another pair had a nest or were building 

 in a hollow of a fallen trunk or nearby, for they would not leave the 

 vicinity even on close approach. 



Skutch (Pac. Coast. Avif., 34, 1960, pp. 166-167) describes behavior 

 and nesting in Costa Rica (ochraceus) , and states nests are placed in 

 cavities on broken ends of decaying branches or trees and that nesting- 

 must begin by April. He found another pair building in late May. 

 Nests of solstitialis in Ecuador were in different sites.
