424 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



ber and December 1956 were captured there again in April and July 

 1963 (Crebbs, Bird-Banding, 1974, p. 264). Like a number of its rela- 

 tives, this species gives low calls that sometimes are repeated rapidly, 

 but does not appear to have a true song. 



Records of specimens from the Province of Panama indicate breed- 

 ing activity is from January to July. A young bird nearly grown was 

 taken at Chiman on February 21, 1950. A female near the Candelaria 

 Hydrographic Station March 12, 1961, was laying; a juvenile just from 

 the nest was collected at Utive March 25, 1949; and near Pacora on 

 April 2, 1950, I watched 1 gathering shreds of bark for nesting ma- 

 terial. The following day 1 worked at nest construction on a small, 

 nearly horizontal branch 20 m from the ground. Skutch (Pac. Coast 

 Avif., no. 31, 1954, pp. 214-216) records a pair that in April and May 

 1935 built three nests in trees about the buildings in the clearing at the 

 laboratory on Barro Colorado Island. The first nest contained two 

 whitish, speckled eggs that soon disappeared. The nest was a cup of 

 plant fibers bound to its support by cobwebs, covered externally by 

 moss. A second nest was built by the female, with the male, who ac- 

 companied her on her flights, occasionally carrying nest material that 

 he gave to her to arrange. This nest also was unsuccessful, but in a 

 third attempt 2 young were reared. They were attended and fed by 4 

 adult birds, with no apparent indication as to which individuals were 

 the parents of the brood. 



Two races separated by characters of color are recognized in the 

 Republic; one of wide range throughout the eastern half, and the other, 

 recently discovered, is known from a few specimens from western Bo- 

 cas del Toro. The nominate race is found in Colombia.
