370 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



tail. Eisenmann has noted that they nest throughout the entire year, 

 as indicated by birds pairing and with young. Males and females, 

 singly or in company, are seen frequently examining old woodpecker 

 holes and other cavities in dead stubs, often high above the ground. 

 On one occasion on March 6, on the Rio Pequeni, back of Madden 

 Lake, I found a pair feeding young in a hole 8 or 10 meters above 

 the ground in a stub standing in the open near the house of a Choco 

 Indian family. 



Dr. Pedro Galindo gave me sections of tree trunk with woodpecker 

 holes collected near Almirante, Bocas del Toro, one on March 27, 

 the other on June 20, in 1962, in which these flycatchers had built 

 their nests. In both the lower quarter or more of the cavity was 

 packed with slender, short filaments of vegetable fiber, mostly dark 

 in color, as a base to support a deep cup made of finer materials. 

 According to Meise ( Schonwetter, Handb. Ool., pt. 15, 1968, pp. 75, 

 91) the eggs (in the nominate race, C.c. colonus) in form are some- 

 what pointed oval, occasionally broader, in color clear white, with very 

 thin shells. Measurements are 18.0-20.8x13.3-14.6 mm. 



As a species Coloniu colonus ranges widely from southeastern 

 Honduras through eastern Central America and South America to 

 northeastern Argentina and southeastern Brazil. The northern sub- 

 species Icuconota is the form of Central America. Colombia west of 

 the Andes, and western Ecuador.
